Montane Softflask 360ml

The Montane Softflask 360 ml is a collapsible TPU soft flask with a 360 ml capacity that weighs just 20 g — a fraction of what a comparable rigid bottle typically weighs, which is why soft flasks are a common choice for trail running, fastpacking, or as a secondary bottle in a pack's mesh pocket. It closes with a high-flow silicone bite valve and is single-wall, uninsulated, with no hydration-tube or filtration compatibility. The material is BPA-free and food-grade certified, and the flask is rated leak-proof and dishwasher safe, which simplifies routine cleaning. Empty, it collapses flat, useful for hikers who prefer to carry it deflated between water sources rather than hauling a rigid, part-empty container. Given the lack of insulation and filtration compatibility, it functions best as a lightweight carrying vessel for plain water rather than as a solution for hot drinks or in-line filtering on trail.
