UltraFlask by HydraPak 450ml

Regular price $39.95

Tax included.

The UltraFlask is an ideal compliment to the Adventure Pack 12L or 20L & P.F.V. Packs. The dimensions on these have recently changed and as a result do not fit as well in the other Packs. We suggest the 600ml which is shorter, a bit wider, and fits in all our Packs.


- Soft Flask, super soft material conforms to any pocket

- Shrinks as you drink, reducing water sloshing
