The Hydriam is a soft, collapsible, reusable drinking flask.

Perfect for storing water in running vests or for a simple way to carry a flask of whiskey up the mountain, the Hydriam is a versatile and lightweight way to carry whatever liquid you need it to.

The Hydriam comes in three different volume sizes, allowing you to fully customize your set up to your needs. All three sizes feature a tapered design that allows them to easily slide into the pocket of a running vest. The back includes markings for measuring out liquids while cooking or mixing your favorite camp cocktail.

Using the same universal 42mm thread as the Vecto, the Hydriam is compatible with filters like the Katadyn BeFree, allowing for filtering on the go during long runs or fastpacking trips.
