The UltraFlask is compatible with hydration vests, belts, or pack pockets, providing bounce-free stability and a flexible flask shoulder to prevent chafing. Its collapsible design allows it to fit easily in any pocket and pack away when empty. The SpeedFill Cap makes it perfect for quick refills at aid stations, with a side tab opening the cap in one motion and snapping shut with a click.

The customizable cap of the UltraFlask allows you to choose between a straw or bite valve, offering versatility for your hydration needs.
