The UltraFlask+ 500ml combines a compact soft flask with a screw-on filtration system, letting you draw water directly from natural sources without carrying separate purification gear. Designed for minimal pack weight, the filter attaches to the top of the flask for direct drinking or can be used to fill a bottle or reservoir when you're carrying larger volumes. The system suits fast-and-light hikers, trail runners, and backcountry travelers who prioritize clean hydration with reduced kit.
