Sea To Summit eVent Compression Dry Sacks
A completely new concept in compression dry bags - there is no valve. This innovation uses an air-permeable base made of eVent waterproof fabric, which allows air to be pushed out of the sack, but won’t allow water to get back in. Suitable to keep contents dry in any wet situation where the bag is not submerged.
We recommend this compression sack for your sleeping bag. Completely waterproof and highly compressible, there really is no better product for ensuring your sleeping bag will stay dry and secure.
