Built for long distance runs at 600mL in volume. The flask has a tapered shape that is compatible with our LF 5L running vest, and features a locking cap so the nozzle does not leak due to pressure while running. Made by HydraPak®.

100ml more!
Love the 600 ml giving you those extra few sips when you need it. Going hard on adventure and packing light means not wasting space, no extra weight and as little extra water as needed. The extra 100 ml is there to get you back to the car when you would have been dry an hour ago.

Love my 600ml flask
Having the large structured shoulders makes refill a breeze.
