Snow Peak Ti-Double 450 Anodized Mug vs GSI Outdoors Infinity Backpacker Mug

The Ti-Double gives more capacity than anything else here at less than half the weight of the steel mugs, because titanium double-wall does the same job as vacuum steel for a fraction of the mass. The GSI is lighter still and cheaper, with an insulating sleeve rather than a sealed wall.

Buy it

More capacity than any mug here at less than half the weight of the steel ones.

• 118 grams for 15.2 fluid ounces, which is the best capacity per gram in this comparison by a wide margin.
• Double-wall Japanese titanium gives real insulation without the mass of a vacuum steel body.
• Foldable handles, so it nests and packs flat rather than taking mug-shaped space in a bag.
• Snow Peak states plainly that the double wall cannot be used for cooking or placed over a heat source, which many brands leave you to discover.

• Cannot go on a stove, so reheating means transferring the drink to a pot and back.
• Premium pricing, and titanium costs a great deal per gram saved.
• No lid included, so it loses heat from the top and spills in a pack.

GSI Outdoors Infinity Backpacker Mug

Buy it

Lightest and largest here, with measuring graduations that make it a second piece of kit.

• 100 grams, the lightest mug in this comparison, holding 17.5 fluid ounces, the most of any of them.
• Volume graduations moulded in, so it doubles as a measuring cup for rehydrating meals and mixing drinks.
• Sealable sip-through lid keeps out trail dust and insects as well as reducing spills and heat loss.
• Lifetime warranty and described as repairable rather than disposable, with a recycled rPET sleeve and BPA-free polypropylene.

• An insulating sleeve is meaningfully less effective than a sealed double wall, so drinks cool faster.
• Polypropylene picks up flavours and stains over time in a way steel and titanium do not.
• No published weight on the product page, so the figure has to come from elsewhere.
