Peak Design Wash Pouch vs Filson Rugged Twill Dopp Kit
Which should you buy? Our verdict on both, pulled from our full The Best Dopp Kits: 4 Compared (and One to Skip) comparison.
Peak Design publishes internal and external dimensions, volume and weight, designs for the spill rather than hoping it will not happen, and backs it with a lifetime warranty. Filson is the one to buy if you want a bag that outlasts the luggage, in waxed twill with a tear strength it will actually quote.

Peak Design Wash Pouch
Buy itDesigned around the spill, documented to the centimetre in both sizes, and covered for life.
- Every dimension published: the Small is 26 by 10 by 13 centimetres externally, 24 by 9 by 13 internally, one litre and 176 grams; the Regular is 2.5 litres and 248 grams. Nobody else here publishes internal dimensions.
- TPU-coated nylon mesh pockets (four in the Small), an internal zip pocket and a magnetically sealed toothbrush pocket, and all of them turn inside out so the bag can be deep cleaned after a leak.
- Sits upright on a counter or hangs from a stowable aluminium hook, sewn with abrasion-resistant thread, and carries a lifetime warranty.
- The one-litre Small is genuinely small, and anyone carrying full-size bottles will want the 2.5-litre Regular.
- Synthetic throughout, which some people simply prefer not to have in a wash bag.
- The hook needs a rail or a hook to hang from, which not every bathroom provides.

Filson Rugged Twill Dopp Kit
Buy itWaxed twill with a published tear strength, lined with coated nylon so nothing escapes into your luggage.
- Rugged Twill with abrasion-resistant fabric whose tear strength exceeds 1,400 pounds, which is the only fabric strength figure published by any maker in this comparison.
- Lightly waxed for water resistance, with a coated-nylon-lined interior specifically to stop spills escaping into the rest of your luggage, and a heavy-gauge rustproof brass zipper.
- Bridle Leather zipper reinforcements and grab handle, plus full-width interior and exterior pockets, five litres of capacity and a Limited Lifetime Guarantee.
- No weight is published, and waxed cotton twill with leather trim is not a light combination.
- One full-width interior pocket is the only organisation; there are no mesh pockets or toothbrush sleeve.
- Waxed cotton needs occasional re-waxing and is wiped or brushed clean rather than washed.
