Inov8 500ml Soft Flask with Locking Cap

The Inov8 500ml Soft Flask with Locking Cap makes leaking bottles during your runs a thing of the past.

This flask has an auto-sealing Phaser bite valve for fast and leak-free hydration and a twist-lock cap. Thanks to the large opening, you can fill and clean the bottle quickly and easily. The bottle shrinks when drinking and is non-bouncing so that the water does not slosh around. You simply fill it and put it in any pocket on your vest, backpack, waist bag or just on your pants for maximum convenience.
