Compact, lightweight, and designed for effortless hydration, the WRELS Folding Soft Flask is ideal for running, cycling, camping, and everyday travel. With a capacity of up to 300 ml, it offers a practical, space-saving solution for short workouts, races, and outdoor activities where minimal weight matters.
Made from food-grade TPU material, this soft flask is 100% BPA-free and PVC-free, ensuring safe, odour-free hydration. The bottle stands upright when full and compresses as you drink, reducing bulk and eliminating water sloshing when empty. A high-flow bite valve automatically seals after each sip, providing leak-free, easy hydration with a light squeeze.
Ultra-light and foldable, the flask fits comfortably into hydration vests, belts, or backpack pockets. It can be chilled or frozen overnight for hot days and is also suitable for holding warm water, making it a versatile choice for sports, travel, and outdoor use.
