The insulated jacket the Unbottle comes in is to me what makes it so great. This extra and thick layer between the reservoir and things that want to puncture it makes it incredibly durable. Great purchase for sure.

Brand recognition comes from being the best in the eyes of the consumer. I use the Unbottle during every stage of my adventure races, not only inside my pack, but lashed to my PFD or rigged up as a stand-alone system in a pinch. Its rugged, insulating outer jacket is key!

this thing works perfectly. And it doesn't say it on this site, but you can take the bladder out of the insulated sleeve. it's just a regular Omega Hydrotanium bladder, which makes this a GREAT value considering you get the sleeve and the Ergo Hydrolock mouthpiece for only 5 dollars more than the bladder by itself.

Bought this bladder to add some toughness to my all-around hydration needs and find it's hard to sneak into a few of the smaller packs or hydration sleeves/compartments within the bigger packs. Other than that, works great and gives much better insulation than the standard non-insulated versions. I've pulled the yellow on/off switch out of the bite valve quite a few times though so be careful with that one as well

i'm a lifeguard, and because i need to be out in the sun all day, this is a solid amount of water that stays cold to keep me cool and hydrated. it's also really useful when hiking, going on picnics, or going to the beach with friends. i drink a lot of water, and this fits in any bag i bring with me!

These types of hydration packs are great for keeping you hydrated on the trail. Much better than stopping, taking of your pack, getting out a bottle, putting the bottle back, putting the pack back on etc.
I have previously used a no-name variant which leaked from the mouth piece and from the bladder lid so upgraded to this well known brand. You really do get what you pay for. I didn't have any major leeks, only a few drips occasionally from the mouthpiece.
The insulated cover was great in keeping the cold river water cold during long periods even in the hot sun. It would be nice to have the tube insulated though as the first mouthful can get quite warm.
The only issue i had was the little plastic link that connects the lid to the bladder broke although has no effect on the operation of the camelbak.

I put this piece through hell in the US Southwest doing geologic fieldwork. It stayed cool, it stayed handy, and it stayed in one piece. And everything of mine goes to pieces. Two thumbs up.
