Perfect dry compression storage to keep gear reliably dry and compact inside a backpack or bike bag. Made from bluesign-approved ultra lightweight Ultra-Sil 30D Cordura® nylon with a C0 non-PFC DWR, and an eVent® fabric air permeable base with a C0 non-PFC DWR finish 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 UL light and simple. Compression straps make it easy to evenly compress soft items, and the hypalon non-wicking roll-top closure also keeps the water out. Simple, extremely light and reliable- the perfect dry compression solution for internal use.
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.
An incredibly lightweight yet durable fabric used in a large number of Sea to Summit products. The 30 denier bluesign Approved nylon is made with CORDURA® yarns for strength. A Non-PFC DWR finish on the outer face helps to shed water.
The inside is polyurethane-coated – in dry bags, the seams are seam-taped.
The hydrostatic head is greater than 2000mm – more than adequately waterproof for the types of environments Ultra-Sil dry bags, stuff sacks and compression sacks are intended for.

Frequently Asked questions
Does this bag work for modular packing in a backpack?
Yes! Use these bags for all compressible items. First, squeeze the air out, then pack the dry bag into a tight space so it doesn't draw air back in. It works wonders on sleeping bags and insulated clothing.
Is this dry bag suitable for paddle sports?
No. Featherweight fabrics are not appropriate for the sharp or abrasive elements in water sports. We recommend Lightweight Dry Bags for general paddle use.
Is this dry bag waterproof?
The body of the dry bag is waterproof enough (2000+ mm hydrostatic head) for use as storage inside a backpack or duffle. However, for water sports or general, external use we recommend compression dry bags with a higher hydrostatic head/more abrasion and puncture-resistant fabrics.
