Soft Flask Collapsible Water Bottle, BPA-Free TPU Folding Hydration Flask with Dust Cover for Trail Running, Hiking & Cycling (8.5, Fluid Ounces)

About this item

• [Quiet & Zero-Slosh Design] Stop the annoying sloshing sound during your runs. This soft flask compresses as you drink, eliminating air and keeping the water steady. It fits snugly in your hydration vest or waist pack without bouncing or chafing against your ribs.
• [Tailored Sizes for Every Mile] Choose your perfect fit: 250ml (8.5 fl oz) for quick sprints or energy gels; 500ml (17 fl oz)—the standard size for most running vests; and 750ml (25 fl oz) for long-distance endurance training and mountain hikes.
• [High-Flow Bite Valve with Dust Cover] Stay hydrated without slowing down. The soft silicone bite valve allows for quick sips with a light squeeze. We added a protective dust cover to ensure your mouthpiece stays clean from trail dirt, mud, and grime.
• [Premium Food-Grade TPU Safety] Built for your health and the planet. Made from 100% BPA and PVC-free TPU material, this flask is tasteless and eco-friendly. The high-frequency welded seams provide superior durability and a leak-proof seal that won’t burst under pressure.
• [Ultra-Light & Space-Saving] Weighing only about 40g (1.4oz), it’s virtually weightless when empty. Once finished, simply fold it up and tuck it into your pocket. It’s the ultimate minimalist hydration tool for trail runners, hikers, and marathoners.
