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. Using the same universal 28mm or 42mm thread as the Vecto, the Hydriam is compatible with many filters (see specs), allowing for filtering on the go during long runs or fastpacking trips.

The Hydriam comes in different volume sizes, allowing you to fully customize your set up to your needs. All 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.

An optional add-on Quick Hydration Kit is a customizable hydration vest set up by mixing and matching the QuickConnect Cap & QuickStraw. Design a hydration kit to the exact specifications of your running vest, your running style, and your preferences.
