Description
Perfect dry compression storage for everything from kayaks, motorbikes, roof racks and beyond. Made from a super-strong, abrasion and puncture-resistant 420D waterproof main body fabric and a 500D Cordura eVent® waterproof but air-permeable base that allows you to push air out while still keeping your contents dry inside. This means no need for a purge valve, making the Evac Compression Dry Bag HD simple to use, even in challenging conditions. Four compression straps make it easy to evenly compress soft items, lash points provide reliable attachment points, and the hypalon non-wicking roll-top closure also keeps the water out. Simple, extremely rugged and reliable- the epitome of durability, versatility, and dry compression.
Technical Features

eVent™ fabric is an air-permeable, waterproof laminate used in Sea to Summit eVac Dry Storage products:
- eVac Compression Dry Bags UL, eVac Compression Dry Bags LW and eVac Dry Bags LW. This laminate utilizes a 70 denier nylon face fabric with a PFC-free DWR finish.
- eVac Compression Dry Bags HD. This laminate utilizes a 500 denier Cordura nylon face fabric with a PFC-free DWR finish.
In both cases, the laminate allows air to be pushed out of the dry bag/compression dry bag but prevents water from entering. This means you can compress the air out of a dry bag without needing a purge valve. (A purge valve adds weight and complexity, and may fail or accidently be left in the 'open' position).
- eVent technology is simple, reliable and foolproof.

All Sea to Summit Dry Bags, Stuff Sacks and Compression Sacks use a durable water repellent finish that is Non-PFC.

This Non-PFC, rugged and durable fabric is used in our Big River Dry Bags and Drypacks, eVac Compression Dry Bags HD, SUP Deck Bag and other paddle accessories. A hefty 420 Denier nylon face fabric is bonded to a bright white TPU lining, giving it a hydrostatic head of 10,000mm, as well as exceptional abrasion, tear, and puncture resistance.

Frequently Asked questions
Is this dry bag waterproof?
The body of the dry bag is waterproof (10,000 mm hydrostatic head). However, avoid submersion since water can seep through the roll-top closure of any dry bag.
Is this dry bag suitable for paddle sports?
Absolutely. The tough nylon material on this dry bag is perfect for water sports. Just be cautious around sharp objects or abrasive surfaces.
Would this dry bag work for overland motorcycling?
Yes! It is rugged, waterproof and has plenty of attachment points - all of which make it great for motorcycling, snowmobiling and (in the smaller sizes) bikpacking.
