Collapsible TPU Soft Flask Water Bottle 250ml / 500ml

Compact Hydration for Running, Hiking and Travel

This collapsible soft flask is designed for active use when every gram and every inch of space matters. Available in 250 ml and 500 ml capacities, it offers reliable hydration for running, hiking, cycling, camping and daily commuting without the bulk of a rigid bottle.

Constructed from flexible TPU (thermoplastic polyurethane), the flask is lightweight yet hard-wearing, with a soft body that compresses as you drink. When empty, it can be folded or rolled to fit easily into a pocket, running vest, waist pack or backpack. A baby-grade silicone nozzle provides a comfortable, safe drinking experience, while the secure cap helps protect the mouthpiece from dust and dirt. The material is BPA-free and suitable for repeated use within a recommended temperature range of 0-40°C.

The 250 ml option is ideal for shorter runs or compact waist belts, while the 500 ml size suits longer outings or day hikes. Both stand upright when filled and shrink as the contents are consumed, reducing sloshing and saving space. The wide filling port allows for quick refills, and the flask can be chilled or partially frozen for a cooling drink in warm weather.
