MULEBAR - Reusable Soft Flask - Silicone Water Bottle for Energy Gel - Trail Running, Marathon & Cycling - Waterproof, Lightweight - BPA Free - 250ml

• RIGHT-SIZED FOR SHORT SEGMENTS – At 250ml, this flask is sized for roughly 5-10km stretches between aid stations, so you carry only what you need without extra weight.
• COLLAPSIBLE & UNBREAKABLE DESIGN – The flexible silicone body compresses as you drink and resists cracking or shattering, unlike rigid plastic bottles.
• ANTI-DRIP VALVE WITH WIDE-MOUTH FILLING – A 5cm-diameter opening makes refilling and adding powder mixes fast and mess-free, while the anti-drip silicone valve with dust cap keeps things leak-proof and hygienic between sips.
• ERGONOMIC ONE-HANDED GRIP – Designed to be squeezed and sipped with one hand while running or hiking, so you never have to break stride to rehydrate.
• LIGHTWEIGHT & TEMPERATURE-RESISTANT – Weighing just 35g and rated from -20°C to +40°C, this BPA and phthalate-free flask is built to perform in any race-day condition.
