The Best Chainsaw Chaps: 4 Compared (and One to Skip)
We compared four currently sold chainsaw leg protectors on the certification actually printed on the label, how much of the leg the pad covers, the lengths and waist ranges offered, and what each maker says about washing and retiring them.
The short version
The Labonville Full Wrap is the pick if you want the most leg covered, because it wraps the leg instead of hanging in front of it, and Labonville still builds them in New Hampshire. The Husqvarna Technical Apron Wrap is the value choice for a homeowner: UL certified to ASTM F1897, apron wrap coverage, a wedge pocket, and it is stocked almost everywhere. Clogger Zero Gen2 pants suit climbers and anyone running a saw all day in heat, but they are trousers you wear all shift rather than something you buckle on for twenty minutes, and 360 degree calf protection is a paid add-on rather than standard. Skip the Oregon 563979 one-size chaps: they are UL Classified and cheap, but a single fixed 36 inch length sold as one size fits all is a fit compromise, and fit is what decides where the pad actually sits. Whatever you buy, check for a genuine UL mark and file number, because UL Solutions put out a warning in February 2026 about chaps carrying a fraudulent UL file number. Best for: anyone who runs a chainsaw on the ground, at any skill level.
Our picks at a glance
- Labonville Full Wrap Chainsaw Chaps (W850KP) - Buy. American made wrap chaps that put the protective pad around the leg instead of only across the front of it.
- Husqvarna Technical Apron Wrap Chainsaw Chaps - Buy. The default homeowner chap: UL certified, apron wrap coverage, a wedge pocket, and available almost anywhere saws are sold.
- Clogger Zero Gen2 Light and Cool Men's UL Chainsaw Pants - It depends. Certified chainsaw trousers built for climbers and all day sawyers, which is a different job from a chap you buckle on and take off.
- Oregon Protective Chainsaw Chaps, Black, One Size Fits All (563979) - Skip. UL Classified and cheap, but a single fixed length sold as one size fits all gives up the one variable that decides where the pad sits.
The verdict in 30 seconds
What mattered most
- Style
- Back of leg covered
- Certification as published
- Protective pad
- Outer shell
- Lengths offered
Chainsaw chaps are not padding. Inside the shell is a pad of long loose fibres, and when a running chain cuts the outer layer those fibres get dragged into the drive sprocket and jam the saw. That is the whole mechanism, and it means two unglamorous things decide whether a pair works: whether the pad is where your leg is, and whether the pad is still clean and uncut. We looked at four leg protectors that are sold in the US right now, judged on published certification, coverage, sizing and the maker's own care instructions.
American made wrap chaps that put the protective pad around the leg instead of only across the front of it.
Best for: Anyone felling, bucking or clearing storm damage often enough that the extra weight is worth having the back and inside of the leg covered.
- Full wrap construction carries the pad around the leg, so a kickback that comes across the inside or back of the thigh still meets protective fibre.
- Five lengths from 32 to 48 inches with a waist adjustable to 46, which makes it far easier to get the hem sitting just above the boot where it belongs.
- 1000 denier Cordura shell on both faces over a six ply Kevlar and polyester pad, and Labonville still manufactures them in the USA.
- Heavy and warm compared with an apron chap, which is a real problem in summer heat.
- Retailer listings for these still cite the 2008 edition of ASTM F1897 rather than the current one, so ask the seller what the label says before you buy.
- Labonville specifies hand washing with non chlorine detergents and hang drying, so you cannot just throw them in the machine.
- Sizing is measured from belt line to the top of your foot, not by inseam, so ordering by your trouser size gets it wrong.
The default homeowner chap: UL certified, apron wrap coverage, a wedge pocket, and available almost anywhere saws are sold.
Best for: The homeowner or part time firewood cutter who wants a properly certified chap without hunting a specialist supplier.
- Husqvarna lists ASTM F1897, ANSI Z133.1, UL certification and compliance with OSHA 1910.266 on the product page itself.
- Apron wrap cut carries protection around the front and onto the sides of the leg, which is more than a flat front apron gives you.
- Five layers of TEK WARP under a PVC coated 1000 denier polyester shell, with a felling wedge and gear pocket and Delrin buckles.
- Wrap is partial. The back of the thigh and calf are still open, unlike a true full wrap.
- Only two size bands, 36/38 and 40/42, with the waist topping out at 42 inches, so tall or large operators are squeezed.
- Husqvarna specifies cold water, mild detergent and hang drying with no chlorine bleach, which is fussier than some rivals.
- Bulkier and warmer than purpose built chainsaw trousers if you are wearing it all day.
Certified chainsaw trousers built for climbers and all day sawyers, which is a different job from a chap you buckle on and take off.
Best for: Climbing arborists and anyone running a saw for hours in heat, who will genuinely wear certified legwear more often if it breathes.
- UL certified to ASTM F1897-20 and meets OSHA 1910.266, so this is real certified protection rather than a work trouser with padding.
- Six layers of Clogger's Arrestex HP fabric using UHMWPE fibre, at about 2 lb 3 oz in a medium, with 140 percent four way stretch.
- Sized XS to 3XL in short, standard and tall leg lengths, which is the widest fit range in this group by a distance.
- Standard protection is front only. The 360 degree calf option costs extra, so the version most people order does not cover the back of the leg.
- You wear trousers for the whole shift. A chap comes off at the truck, which many ground workers actually prefer.
- Priced well above any chap here, and a torn pair is a whole garment replaced rather than a chap swapped out.
- Fit matters more than with a chap, because you cannot cinch a trouser leg into position the way you can a strap.
UL Classified and cheap, but a single fixed length sold as one size fits all gives up the one variable that decides where the pad sits.
Best for: Almost nobody as a first choice, though it is defensible as a spare pair kept in a truck for a visitor whose size you do not know.
- UL Classified, so a third party has evaluated it rather than the seller simply asserting a standard.
- Eight layers of breathable warp knit under a 600 denier Oxford shell, and Oregon says it is machine washable.
- Waist adjusts to 46 inches and the length adjusts a little at top snaps, which covers a slice of the size range.
- Oregon publishes one length, 36 inches, for every buyer. Chaps only protect where they are, and a hem that stops short of the boot top or drags on the ground is a real loss of coverage.
- Apron style, front only. There is no rear or calf coverage in this SKU, so an inside or back of leg contact meets trousers.
- The top snap adjustment shortens the garment from the waist, which moves the whole pad up the leg rather than trimming the hem.
- For a modest step up in price you can buy a chap sold in three or more discrete lengths, which is a better use of the money than eight layers.

How we judged the field
Five things decide whether a pair of chainsaw chaps does anything for you. First, certification: the label should name ASTM F1897 and carry a genuine UL mark and file number, because that is the only evidence anyone has actually run the garment through the F1414 cut test rather than sewing thick fabric together. Second, coverage: the standard sets minimum pad dimensions, but the standard cannot make the pad sit over the part of your leg the chain reaches, and a front apron leaves the back and inside of the thigh with nothing but trousers. Third, length and size range, which sounds like a comfort issue and is not. The hem needs to sit at the boot top, and a maker who offers three or five lengths lets you get there in a way that one universal length cannot. Fourth, the shell, because the pad is only protective while it is clean and dry, and a tough coated shell is what keeps bar oil and sawdust out of it. Fifth, the care instructions the maker publishes, since bleach and pressure washing measurably degrade cut-through protection and every brand here words its washing advice differently.
The field splits three ways, and the split is more about how you work than how much you spend. Apron chaps are the cheap, common answer: a flat panel across the front of each leg, easy to strap on, easy to shed. Wrap chaps carry the pad around the leg and cost more in weight and heat. Chainsaw trousers are certified legwear you wear all shift, which is the right answer for climbers and the wrong answer for someone who does four hours of firewood a year. We took one strong example of each, plus the budget apron chap that most casual buyers actually put in the basket, so the comparison reflects the real decision rather than a spec sheet contest.
Labonville Full Wrap Chainsaw Chaps (W850KP) - buy
The Labonville Full Wrap is old fashioned in the way life-safety kit often should be. It is built in New Hampshire from a six ply Kevlar and polyester pad under a 1000 denier Cordura shell on both faces, so oil and abrasion stay off the fibres. What earns it the top spot is geometry rather than layer count: the panel wraps the leg instead of hanging in front of it, so contact across the inside of the thigh or the back of the calf still meets protective fibre. It comes in 32, 36 and 40 inch lengths with 44 and 48 to order, and a waist adjustable to 46, which is the range you need to get the hem sitting just above the boot rather than dragging. The costs are real. It is heavy at four to five pounds and it is hot, the care instruction is hand washing with a non chlorine detergent and hang drying, and retailer listings still cite the 2008 edition of the ASTM standard, so ask what is printed on the label. This is for the person cutting often enough to want the whole leg covered.
Husqvarna Technical Apron Wrap Chainsaw Chaps - buy
The Husqvarna Technical Apron Wrap is the chap most people should default to, and the reasons are unglamorous. Husqvarna states ASTM F1897, ANSI Z133.1, UL certification and OSHA 1910.266 compliance on its own product page, which is more than a lot of listings manage. The construction is five layers of TEK WARP under a PVC coated 1000 denier polyester shell, with acetal Delrin buckles and a pocket sized for a felling wedge, and the apron wrap cut takes protection around the front and onto the sides rather than leaving a flat panel dangling. It is stocked at essentially every Husqvarna dealer and a lot of general retailers, which matters more than it sounds, because the chaps you can actually try on for length are the ones that will fit. The limits are the fit range and the coverage. Two size bands, 36/38 and 40/42, and a waist that stops at 42 inches, leaves larger operators out. And this is not a full wrap: the back of the thigh and calf are uncovered. For a homeowner or weekend firewood cutter, that is a sensible trade.
Clogger Zero Gen2 Light and Cool Men’s UL Chainsaw Pants - it depends
Clogger Zero Gen2 pants are the answer to a question chaps cannot answer, which is what you wear when you are running a saw for eight hours or hanging in a harness. They are UL certified to ASTM F1897-20 and meet OSHA 1910.266, so this is genuine certified legwear, built from six layers of Clogger’s Arrestex HP fabric using UHMWPE fibre rather than aramid, at around 2 lb 3 oz in a medium with 140 percent four way stretch. Sizing runs XS to 3XL in short, standard and tall legs, which is the best fit range here. Two things stop this being a straight recommendation. The standard build is front protection only, and 360 degree calf coverage is a paid upgrade, so the version most people order covers less of the leg than a wrap chap does. And trousers are a commitment: you cannot buckle them on for twenty minutes and take them off at the truck, and a chain strike retires the whole garment. If heat or climbing is why you have been skipping leg protection, this fixes that. Otherwise it is a lot of money for less rear coverage.
Oregon Protective Chainsaw Chaps, Black, One Size Fits All (563979) - skip
The Oregon 563979 is the pair a lot of people buy without thinking about it, and the reason to skip it is in Oregon’s own specification. It is a decent apron chap on paper: UL Classified, eight layers of breathable warp knit under a 600 denier Oxford shell, machine washable, and a waist that adjusts to 46 inches. But Oregon publishes exactly one length, 36 inches, and sells it as one size fits all. Chaps only protect the part of the leg they are covering, and every serious source on the subject, from the Forest Service to STIHL’s own fitting advice, says the hem should end around the boot top and no lower. A universal 36 inches will be too long on plenty of people and too short on plenty of others, and the top snap adjustment shortens the garment from the waist, which slides the whole pad up the leg rather than trimming the hem. Add that it is a flat front apron with no rear or calf coverage in this SKU, and the modest saving buys you a fit compromise on the one thing you cannot fix afterwards.
Labonville Full Wrap Chainsaw Chaps (W850KP) vs Husqvarna Technical Apron Wrap Chainsaw Chaps: which should you buy?
Both of our buy picks are properly certified chaps, so the choice is not about whether they work. It is about how much of your leg you want covered and what you are willing to carry to get it. The Labonville wraps the leg, which means an inside-of-thigh or back-of-calf contact still meets protective fibre, and it comes in five lengths so you can actually get the hem to the right height. The Husqvarna is an apron wrap: protection across the front and around onto the sides, nothing behind, in two broad size bands. In exchange the Husqvarna is lighter, cooler, has a wedge pocket, and is sitting on a shelf at your local dealer where you can hold it against your leg before you pay.
Here is the practical way to choose. If you cut for more than a few hours at a stretch, work on slopes or in blowdown where the saw ends up in awkward positions, or you are 6’2” or 5’6” and a standard chap has never sat right, buy the Labonville and accept the weight. If you are dropping a few trees a year, bucking firewood on flat ground in warm weather, and the honest risk is that heavy chaps stay in the shed, buy the Husqvarna, because certified leg protection you actually put on beats better leg protection you do not. One rule applies to both: measure from your belt line to the top of your foot before ordering, not your trouser inseam.
What to look for
- A real UL mark and file number: the label should name ASTM F1897 and carry a UL mark with a file number you can check against UL’s certification database, because UL Solutions warned in February 2026 about chaps sold online with a fraudulent file number.
- Length before layer count: a maker offering three or five discrete lengths is giving you something a maker offering eight layers in one universal size cannot, since the hem needs to end around the boot top for the pad to be where the chain goes.
- Where the pad wraps: apron chaps cover the front, apron wrap adds the sides, full wrap carries protection around the leg, and only the last one puts fibre behind your calf.
- A tough coated shell: oil soaked into the pad acts as an adhesive and reduces protection, so a heavy denier coated outer that keeps bar oil and sawdust out is doing safety work, not just wearing well.
- The washing instructions on the garment: they differ by brand, from hand wash only to machine wash warm and tumble dry, and bleach or a pressure washer will degrade the pad in any of them.
- Buckles and straps you will actually fasten: loose chaps shift out of position, and the Forest Service is explicit that a snug fit and correct length are what maximise the protection you paid for.
Our final take
Chainsaw chaps are one of the few pieces of safety kit where the cheap version and the good version work by exactly the same mechanism. The difference is where the pad sits and whether it is still in good condition. Buy something with a genuine UL mark and an ASTM F1897 reference, buy it in a length that puts the hem at your boot top, keep bar oil out of it, and retire it the moment the pad itself is cut. The Labonville Full Wrap is the most protection here and the Husqvarna Technical Apron Wrap is the sensible everyday answer. Do not let a low price talk you into a one-size garment, and do not let the heat talk you out of wearing anything at all.
Questions, answered
Does OSHA actually require chainsaw chaps, and does that apply to me at home?
OSHA 29 CFR 1910.266 is the logging standard, and it says the employer shall provide at no cost, and assure that each employee who operates a chain saw wears, leg protection constructed with cut-resistant material such as ballistic nylon. It also says that protection has to cover the full length of the thigh to the top of the boot on each leg. That is an employer duty in logging operations, so it does not reach you cutting firewood in your own yard. It is still the benchmark everyone in the trade works to, and it is worth knowing that the regulation names a material property rather than naming ASTM F1897 or a Forest Service specification. Buying to the ASTM standard is how you satisfy the spirit of it.
What does ASTM F1897 actually require?
F1897 is the US specification for leg protection for chain saw users, and the current edition is F1897-25. It sets minimum requirements for the design, performance, testing and certification of garments and devices meant to give cut resistance to a saw operator's legs, and it covers protective area, labelling and care instructions as well as the cut test. The cut testing itself is run to ASTM F1414, using a petrol saw with a 20 inch bar and 0.375 inch pitch chain on a rig with a seven tooth drive sprocket, with the power left on at the moment of contact. F1897 can be reported either as a simple pass or fail at a specified chain speed, commonly 2,750 feet per minute, or as a CS50 threshold, meaning the chain speed at which the probability of cutting through is 50 percent. For chaps, F1897 also sets a minimum pad length of 700 mm and minimum widths at the midpoint and bottom of the pad.
Is a UL mark the thing I should look for?
Yes, and it is worth checking properly rather than glancing at it. UL is the third party that certifies chainsaw leg protection to ASTM F1897 in the US and to ASTM F3325 in Canada, and STIHL, Husqvarna, Labonville, Notch, Clogger and Oregon all state UL certification or classification on their own material. The reason to look closely is that in February 2026 UL Solutions published a warning about chainsaw chaps sold online under the GDLIN and Proyama names that carried a fraudulent UL file number, and advised owners to take them out of service. The label should carry a UL mark, a file number and the ASTM standard, and you can check a file number against UL's own certification database. Buying from the manufacturer or an established forestry supplier is the simplest way to avoid the problem.
Do chaps still work with a battery or electric chainsaw?
The concern is reasonable on the face of it, because a petrol saw stops partly by the clutch letting go under load, and a brushless motor does not have a clutch. It has been tested, though. During the development of ASTM F1897-25, side by side standardised testing was run with both petrol and battery saws, and certified chaps stopped both. The USDA Forest Service National Saw Program issued a bulletin summarising this and noting that the viral videos showing chaps failing generally used retired or damaged chaps and non standard setups. F1897-25 was published in December 2025 and adds an appendix on battery saw performance. Two caveats are fair: high end professional battery saws make more torque than the consumer units in those videos, and STIHL still words its own UL classification as applying to operators of gas-powered chainsaws, so read your own label.
If a saw cuts my chaps, can I patch them and carry on?
It depends entirely on what got cut. A hole or tear in the outer shell alone is repairable, and the Forest Service actually recommends patching shell damage promptly with a flexible urethane sealant so oil and sawdust cannot reach the pad. Damage to the protective pad itself is different. Labonville tells owners to remove chaps from use and replace immediately when the chap or pad is cut in any location, and the Forest Service retires chaps once the first layer of the pad has a cut longer than one inch. Never stitch through the pad to repair it, because that pins the fibres in place and stops them being dragged into the sprocket, which is the entire mechanism. If the fibres have been pulled by a chain strike, that pair has done its job.
