I have hydration backpacks too, but there are times when having the whole pack is overkill and the smaller Unbottle works better. Of course you can also drop it inside an existing pack, put it in a gym bag, attach it to your fishing tackle bag, strap it to your bike frame, strap it onto your desk chair at work - the possibilities are pretty wide open. The four strap clips allow you to clip this onto a backpack or any other implement which has straps, or you can supply your own straps and attach this just about anywhere you might want to. The insulating sleeve holds the hydration bladder, which has a detachable tube with a mouthpiece on the other end. It consists of an outer insulating sleeve with four clip-on strap holders, a top clip-on loop, and a bottom strap. The Camelbak Unbottle, available in 2 or 3 liter capacities/sizes, is a cleverly designed piece of gear which allows you to add hydration in just about any situation. Insulated versions are not the smallest or lightest out there, but provide a nice option for those that want it. Finally, for the same stated bladder capacity, the newer version seems to hold less water than the older version.Īll things considered, these are nice systems. Overall the unit seem more bulky, in spite of the bladder baffle. However, I don't find the current side rings that helpful they tend to get hung up when trying to slip it in and out of packs. I especially like the re-tooled threading on the opening that allows secure opening/closing with only about a quarter turn, and the internal baffle that keeps the bladder from becoming a round balloon. I like the quick-detachable tube, the buckle on the handle, and the fold-out wings at the opening (when folded down they allow faster drying after cleaning).

The more recent model has more bells and whistles, some are helpful and others I'm ambivalent about. An insulated tube is available for use in winter (or summer too, since liquid in the tube can get hot in really warm temps). I liked the simplicity of the no-frills design, large opening that allowed easy cleaning, and pretty light weight for an insulated bladder system. The first one I purchased and used had simple D-rings on the sides, a hose and handle without the current quick detachable feature, an unbaffled bladder, and no fold-out drying wings.

The Unbottle has gone through several design iterations.
