Sea to Summit Evac Compression Dry Bag 20L (High Rise RCS) compresses large soft items using an eVac® base that forces air out while keeping water out, reducing pack bulk for extended trips.
Overview:
The Evac 20L Compression Dry Bag is built to streamline packing for multi-day outings by combining waterproof storage with effective compression. The eVac® base technology provides a waterproof yet air-permeable surface that allows trapped air to be expelled through the base when compressed, eliminating the need for purge valves. The body typically uses ultralight Ultra-Sil 30D nylon with a PFC-free DWR finish, and seams are double-stitched and tape-sealed to protect contents from moisture. Multiple reinforced compression straps with ladderlocks and side-release buckles let you compress soft kit evenly and hold it down for transport, while the roll-top closure with Field Repair Buckle secures the seal.
Aimed at backpackers and travellers who need to reduce packed volume of bulky clothing and sleeping gear, the Evac 20L balances low weight with smart compression hardware. Note that Evac bags prioritise internal organisation and compression rather than continuous deck mounting or submersion use.
What We Love
The standout is the eVac® base — it lets you push out air and dramatically reduce volume with a simple squeeze. The combination of ultralight fabric and multi-strap compression delivers usable space savings without complex valves.
