Tailwind Nutrition Soft Flask

Because the flask is designed to compress as you drink, it eliminates the air space inside the container. This prevents liquid from moving around, which significantly reduces sloshing and bouncing compared to rigid bottles.

Yes, the flask is fully collapsible. Once you finish your fluids, it can be folded or rolled down to fit into a pocket or pack, making it an excellent choice for minimalist setups or races where you need to save space.

The flask is constructed from lightweight, durable plastic designed to withstand the rigors of active use. While it is thin to ensure flexibility and low weight, it is built to handle repeated filling and collapsing without compromising integrity.

With a 0.5L capacity and a flexible, soft-sided design, this flask is compatible with most standard hydration vests and belts. Its pliable shape allows it to mold into tight pockets where rigid bottles might struggle to fit.

The flask features a translucent design, allowing you to see exactly how much liquid remains at a glance. This removes the guesswork during long efforts and helps you manage your hydration strategy more effectively.
