Heh, it is kinda spooky isn't it? One reviewer at backcountry.com apparently plans to stuff this thing in his backpack without the "weighty" slide-lock, relying only on the zipper. I wonder what will happen when someone sits on it?

Still, reports regarding closure security (when properly used) sound promising.

Holy cow! I had the owner of my local gear shop throw a 2L camelbak on a hanging scale, and it weighed in at 13oz. Quite a difference.

Ah, that makes sense, and is a deal-breaker for me. I'll try the standard Platypus bladder.

Thanks for the tips and suggestions!
