2 Pack Soft Flask 500ml/17oz, Collapsible TPU Soft Water Bottle for Running Vest & Hydration Pack, Leak-Proof Running Flask with Bite Valve for Marathon Hiking Cycling (Orange)

About this item

• TWO 500ml / 17oz FLASKS – THE RIGHT SIZE, NO GUESSING: This set includes two full-size 500ml (17oz) soft flasks – not 250ml minis – each measuring about 11x3.5 inches. They drop into standard running-vest front pockets, so you can carry water in one and electrolytes in the other.
• STAYS LEAK-PROOF IN YOUR PACK: A self-sealing high-flow bite valve plus a secure screw-down cap with a tethered dust cover keep water inside, not on your gear. Push the valve closed and tighten the cap fully, and the flask won't drip in your vest, bag, or pocket – no wet stress points, no soaked phone.
• SOFT, EASY-SQUEEZE TPU THAT SHRINKS AS YOU DRINK: Made from soft, flexible TPU that's easy to squeeze and gentle on your hands – not stiff plastic. Each soft water bottle collapses as you drink, so water never sloshes, bounces, or rattles, then folds flat when empty to save space.
• FAST TO FILL, SIP & CLEAN: Bite and go for hands-free hydration without breaking your pace; the cap unscrews completely for quick refills at aid stations and easy rinsing inside and out – no narrow neck to fight at the water station.
• FITS RUNLIX & MOST RUNNING VESTS – BUILT FOR EVERY MILE: Sized to fit RUNLIX hydration vests and most standard running vests, hydration packs, and run belts. A lightweight, durable, packable soft flask for running, marathons, trail, jogging, hiking, cycling, climbing, gym, and travel – for women and men.
