Built to hit the volume sweet spot for many runs at 650mL in volume. The bottle features a locking cap so the nozzle does not leak due to pressure from the belt. Made by Hydrapak.

The larger capacity, the wide opening and the locking cap make this the best soft flask in my opinion. I bought three of them with the LF 5L vest and they fit in the pockets in back along with the two chest flasks up front beautifully. Max hydration capacity without a bladder.

The best lightweight flask
This is the best lightweight flask to use on any of my adventures out in the backcountry or any other activity I might need it. The locking cap is essential as the other versions do not have it and that makes this product far superior. Raide does it again like they do with every product solving a problem and making my backcountry ski adventures even better.
