Key Features

• Ultralight & Collapsible: Crafted from ultralight, flexible food-grade TPU, this bottle rolls smaller than your palm at negligible weight, solving bulk issues of traditional bottles. 300ml slips easily into pockets or waist packs; 500ml integrates perfectly with hydration backpacks or vests. Simply squeeze the bottle and bite the valve for one-handed drinking. Hydrate on the move without breaking stride.
• Durable & Reliable: TPU delivers exceptional flexibility and resilience, resisting drops, wear, and repeated folding. It stays tough even in extreme cold, ensuring reliability in harsh conditions. Tasteless and BPA-free, it keeps water fresh. Silicone-gasketed threaded cap and self-sealing bite valve prevent leaks during intense movement.
• Comfortable Hydration: The 1.65-inch wide mouth makes filling, cleaning, and adding ice easy, and is compatible with most water purifiers. Soft silicone bite valve offers a comfortable bite and smooth flow. A removable dust cap keeps the mouthpiece clean. The bottle dynamically conforms to your body in a pack or pocket, minimizing bounce and chafing.
• Two Sizes for Your Activity: Choose 300ml for short, lightweight activities like morning runs, urban cycling, or casual walks. Choose 500ml for endurance activities like trail running, backpacking, long-distance biking, or marathon racing. Pick the right capacity for your intensity and duration, and hydrate effortlessly to boost performance and reduce fatigue.
