The UltraFlask™ is an ideal compliment to the PFV and other packs. The dimensions on the 450ml is taller than the 600ml, so we do generally suggest the 600ml for most packs.
You can quickly stash the flask in your front chest pocket for access on the fly plus it comes with an optional use 4" hose. Quickly take it off if you just want the bite valve, or if you want the hose leave it as is!
