The SOFT FLASK is a flexible flask that compresses as you drink to eliminate water bouncing inside. Reduces sucking effort. The valve won’t leak until you bite it.
Quick and easy to remove from all pockets or comfortable to run with when paired with a hand support that you can find in our Running section.
Once contents are consumed, the flask can be compressed small and carried light. Can hold gels and formulas as well as regular fluids.
With a collapsible design, molded tops and bottoms, RF-welded seams, and durable TPU construction, the SOFT FLASK 250/500ML safely and conveniently carries up to 500ML of water or other fluids. Measuring 7.75” x 3.5” when full, the flask collapses almost entirely when empty.
The Soft Flask is equipped with a 42 mm-wide screw cap and a high-flow rate silicone bite valve. The TPU construction of the flask is both BPA and PVC-free. An integrated dust cover protects the bite valve and a finger loop attachment makes carrying easy.
