Polar Bottle has added a new hydration solution for mountain bikers; the Session Muck. At a compact 15 ounces, the Session Muck is designed to fit any frame size and/or full suspension bike that traditionally has limited real estate for water bottles and it still fits in a regular bottle cage.
Polar Bottle Session Muck Water Bottle for MTB
Some full suspension mountain bike frames, especially the smaller frame sizes, have very little clearance inside the front triangle for a water bottle. Having never been too concerned about the aesthetics of my mountain bikes, I have done a great job of wearing away the decals of the RockShox Super Deluxe Ultimate on my Revel Rail. How? By repeatedly loading up the bottle cage with a bottle that is, on paper at least, too large for the frame. The extra water adds a lot more to my riding experience than a shiny sticker on the air can ever will.
Most folks are better bicycle owners than that, keen to keep everything spick and span. If your bike is tight on front triangle real estate, the Polar Bottle Session Muck could be a viable option for you. By my book, fifteen ounces, or ~440ml, is much better than nothing.
The Session Muck has some nice features that any off-roader will appreciate. Namely, the Muckguard cap designed to keep the bite valve clean from whatever the trail dishes out. It opens and closes with one hand, sealing the valve when closed. Polar Bottle give their bite valve a fancy name; the Surge Valve, meant to offer a superior flow rate. It is also said to self-seal, eliminating spillages.
The bottle has a single-wall, thus is not insulated, and is made from a BPA-free polymer that is said to be easy to squeeze. It is designed and produced in Colorado.
