CNOC Hydriam Collapsible Flask 28mm - is a flexible, reusable, and collapsible drinking flask designed for a variety of adventures. Whether you're storing water in your running vest or bringing a flask of whiskey to the summit, the Hydriam offers a lightweight and versatile solution for carrying your favorite liquids.

Available in 3 sizes, the Hydriam lets you customize your hydration setup to fit your needs. Its tapered design makes it easy to slip into running vest pockets, while measurement markings on the back are perfect for precise cooking or mixing drinks at camp.

Featuring a universal 28mm thread, like the Vecto, the Hydriam is compatible with popular filters such as Sawyer and Platypus QuickDraw. This makes it an excellent choice for filtering water on the go, whether you're on a long run or a fastpacking adventure.
