Sea to Summit Evac Compression Dry Bag

Sea to Summit Evac Compression Dry Bag UL – 8L / 13L / 20L

Lighter. Drier. Smaller. Smarter.

The Evac Compression Dry Bag UL is your go-to solution for keeping gear dry and compact inside your bike bags or backpack—without the weight penalty. Made from bluesign®-approved 30D Ultra-Sil Cordura® nylon, it’s paired with an air-permeable eVent® base that lets air out but won’t let water in. That means no purge valve, no fuss—just roll it, compress it, and ride.

This bag shines when used inside larger bikepacking or hiking setups, helping you compress sleeping bags, clothing, or other soft items while staying reliably waterproof (note: not intended for submersion). Four compression straps with ladderlock and side-release buckles ensure an even, bulge-free pack every time.
