Sea to Summit Evac Heavy Duty Compression Dry Bag

The Evac Heavy Duty Compression Dry Bag pairs a 420D ripstop body rated to a 10,000mm hydrostatic head with Sea to Summit's air-permeable eVac base, so rolling the top closed pushes trapped air out while keeping the contents genuinely waterproof. Four compression straps then squeeze the packed volume down further once the air is gone. At 420D and 10,000mm, this is built tougher and more water-resistant than Sea to Summit's lighter stuff sacks, aimed at sleeping bags or clothing that need real protection on canoe trips, rafting or wet, abrasive terrain rather than dry-weather backpacking where a lighter sack would do.
