I used to sell both, but now only sell Camelbak's military line.
Reason: The bite vavle on teh BHI product sucked....air, that is.
The push-pull on/off aspect of their bite valve eventually stopped sealing against the incursion of air when I tried to use it...meaning I got about 1/2 air, 1/2 water, at best. I bled the bladder three times before I figured out where the leak was. If I pulled the bite-valve out as tight as I could get it, it would seal out the air, allowing for normal drinking.
Pain in the neck and certainly not something I want my customers having to worry about.
So now I only carry CBs.
In the interest of full disclosure, however, I had a CB Thermobak in Desert Camo leak out of the cap when it was under pressure (such as in a backpack full of gear). A call to Camelbak and in three days I had a new screw-top for the unit.
