The Sea to Summit Evac Dry Bag is a specialized waterproof storage solution designed with an air-permeable eVent fabric base. This construction allows air to be pushed out through the base for compact packing, while maintaining a waterproof seal. The design features a roll-top closure secured with a field-repairable buckle, fully taped seams, and a D-ring attachment point. The bag is constructed from 70D nylon fabric to balance durability and weight, featuring an oval base profile to prevent rolling and aid in stable packing inside packs or kayaks.
