Product features

1. Leak-proof & Bite-Valve Design: Our soft flask features an easy-sip bite valve – just bite gently to drink, and it auto-seals to prevent any drips or spills. Whether you're sprinting on the road or tackling trails, this running water bottle stays completely leak-proof, so you can hydrate on the move without losing focus.
2. Ultra-Light & Foldable: Weighing only around 30g, this soft water bottle running solves the problem of carrying heavy, rigid bottles. Made from flexible food-grade TPU, it can be easily rolled up or folded when empty – perfect for stashing in your running waist belt or race vest. As you drink, the bottle shrinks with the water level, eliminating annoying sloshing sounds.
3. Easy to Fill & Hold: The upper part of our running bottle is made from a firmer material, making it simple to grip and fill even with wet hands or at a water station. No fumbling – just quick, hassle‑free refuelling during long runs.
4. Multi-Capacity Options: Choose the size that fits your distance: 250ml for short jogs, 350ml for mid‑week runs, or soft flask 500ml for marathon and ultra training. The 2‑pack gives you a spare or lets you mix capacities.
5. Safe for Every Run: Crafted from premium food‑grade TPU, this running bottle contains zero BPA or harmful chemicals. The soft, skin‑friendly material contours to your body when placed in a belt or vest, and won't chafe or bounce.
