I like the previous hydrastorm bladder better - BlackHawk HydraStorm Anti-Microbial 100oz Hydration Bladder

Overall I really like this replacement to the one I've been using for almost 10yrs now, but the QD hose fittings are both good and bad. At first glance they are really nice for removing the hose, but the spring loaded stoppers make it REALLY hard to clean the hose fully and letting it dry is now a pain. The new style bite valve is really nice, but the shutoff could be easier to operate with one hand. And there is no dirt/dust cover for the bite valve...so once again you put your mouth on the dirtiest possible point to get water...this makes NO sense. That OTHER brand has this part right, but sadly their covers will not work here and I cannot seem to find a cover suitable for the Hydrastorm bite valve.

On the other hand the antimocrobial material is tough as nails and I like the anti-germ factor. Makes cleaning up easier and more reliable. Believe me when I say I've had some nasty reservoirs in the past! Sadly the new larger mouth won't fit through the hole in my original carrier, but I can figure a way to live with that. That being said, the new larger mouth is nice.
Pros: Anti-germ material, tough, larger mouth, QD fittings, bite valve style
Cons: QD fittings, no dust/dirt cover for bite valve
