Sea To Summit Evac Ultralight 3 Dry Compression Sack - 3 Litri

The Sea To Summit Evac Ultralight 3 is a lightweight, waterproof compression sack designed for backpackers, kayakers, and travelers who need to keep gear dry and compact. With a 3-liter capacity, it is ideal for clothing, sleeping bag liners, or small accessories. The unique combination of a waterproof body and a breathable eVent fabric base allows air to be expelled during compression while preventing water ingress, resulting in a smaller pack size without sacrificing dryness.

Advantages

Ultra-lightweight at just XX grams, the Evac Ultralight 3 uses 30D Ultra-Sil nylon for the body and 70D eVent fabric for the base, offering exceptional durability and waterproofing. The Hypalon roll-top closure with a field-repairable buckle ensures a secure seal, while fully seam-sealed construction guarantees no leaks. The D-ring attachment point allows easy clipping to packs or gear loops.

• Backpacking and hiking trips where weight savings are critical

For best results, roll the top at least three times before buckling to ensure a watertight seal. The eVent base allows air to escape, so compress the sack by pushing down on the base while rolling the top. Store the sack away from sharp objects to prolong fabric life.
