SOFT FLASK

Tailwind UltraFlasks™ Soft Flasks, designed in collaboration with HydraPak, are designed to conform to the shape of your body, compressing as you drink - this means reduced sloshing and bouncing, less spillage, and an easier time drinking Tailwind. The clear design eliminates guessing how much hydration you have left and when it's empty, the pliable body of the flask collapses into the hard top, making this the perfect bottle for multi-stage events. Capacity - Holds up to 500ml/17oz Vest-pack fit provides bounce-free stability and a flexible flask shoulder to prevent chafing. Leakproof high-flow bite valve auto-seals after each sip, eliminating annoying drips. Shrinks as you drink to minimize water bounce. Made of ultra-durable, abrasion resistant TPU.
