Used by the US Coast Guard in their survival kits, Osmo Seal is the most important addition to any "ditch bag". The Osmo Seal uses forward osmosis technology to filter fresh or saltwater, creating a nutritious, grape-flavored sports drink. Each Seal pouch fills up to 450 ml of water-based hydration. Osmo Seal takes up 1/3 of the space of package water, and each pouch comes complete with vitamin C, electrolytes and 200 calories of nutrients. It also has a 7 year shelf life so it will be ready when you need it!
