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 eVac® 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.

Technical Features

• Non-PFAS: Sea to Summit sleeping bag fabrics and insulation are made without PFAS compounds. The non-PFAS DWR finish on the shell helps prevent the insulation from becoming damp if the bag comes into contact with moisture, such as tent wall condensation.Ultra-Dry Down is a non-PFAS hydrophobic treatment that absorbs less moisture and dries more quickly. It does not affect the 'breathability' or the lifespan of the down and lasts through at least 20 washings. The down used in our sleeping bags is responsibly sourced.Sea to Summit Dry Bags, Stuff Sacks and Compression Bags use a non-PFAS Durable Water Repellent finish to help shed water. Big River bags use a non-PFAS PU coating.
• eVac Fabric: Evac 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 non-PFAS DWR finish. 
  Evac Compression Dry Bags HD. This laminate utilizes a 500 Denier Cordura nylon face fabric with a non-PFAS 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). 
• 30D Ultra-Sil: 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.
