Using on my trike

I needed a water pack but riding an ICE trike bicycle a backpack won’t work. The insulated cover gave me the connections to attach, and keeps the water cool.

I purchased for my husband who is 6’2 with broad shoulders. It has been a struggle to find something that fits. I would recommend you make an large or extra large one.for larger men.

Almost Perfect...

I really like my Unbottle 2L. The design is great, the clips are a pleasant feature if you need to hang it somewhere, the insulated pouch keeps your fluid cold, and the bite valve and tube are perfect. Works great! BUT... the other reviews I read about the screw cap on the bladder are true. Getting it to seal properly is problematic. It's so easy to cross thread that it's an issue almost every time. Surely Camelbak can come up with an improved solution! You can't visually tell if you have sealed it properly or not, so you have to squeeze the bladder to see if any fluid leaks out. Other than that setback, I do really like it. I use it in my Ultimate Direction 6.0 Ultra vest and it's a perfect match!

Same but different

Basically the same unbottle keeping the quick tube connect/disconnect from my last unbottle but made improvement to the screwcap since my last unbottle.

Going on 22 years strong

I've owned an Unbottle 100 since 2000. I'm on this site to buy a new Pure Flow tube for it and am giddy to see it is still being made. Mine is an older look (solid navy sleeve) but It has become the best auxiliary reservoir. Never leaks, insulated, and bombproof. It lives in a shed all year in the Phoenix heat. I throw it full of water all the time, and it refuses to die. The original screw top is really hard to get on/off, but that is fine since I know it never leak. I'm still using the original bite valve. This piece of gear has been with me for so many memories that I can't ever get rid of it. Its like an old hat that fits perfectly. Roadtrips, work, work commutes, motocamping, band camp, scouts, paddling, big hiking trips, and on and on. I need 5L for an upcoming summit, and its perfect to throw into my primary 3L daypack. Camelbak, if you're reading this, when did you start making this thing? I think mine is officially vintage :D

The lids are terrible

The large lids are terrible. They cross thread almost every time and jamb easily. I can’t believe this is been going on this long and you haven’t fixed them.

Works great

I bought this to fit on my wildland firefighting pack. It’s the perfect size, and the clips make it easy to attach to my pack. The insulation keeps my water cool, and the quick disconnect on the hose makes it easy to refill. Great little hydration pack.
