USWE Nordic 10L, Ski Backpack, Winter Snow Hydration Pack with 2.0L/ 70 oz Water Bladder, for Men and Women. Insulated with Thermo Cell Freeze Protection. Bounce Free, Model 2.0, Black

The Nordic 10 is a revolutionary Winter Backpack with Thermo Insulated Hydration for Extreme Cold. The hydration pack is developed to prevent the water in the tube and bite valve from freezing down to -15 ¡F (-26 ¡C). The backpack is equipped with the Thermo Cell technology in a multilayer insulation cover, that reflects the heat on the inside and shields from the cold and wind from the outside. By its design, the Thermo Cell Technology closes tightly to the body and a thin mesh membrane permits maximum body heat to pass through. Used in this way the body heat fuels the Thermo Cell with thermal energy. The USWE winter backpack is geared-up with the award winning No Dancing Monkey 4-point harness, that makes the pack 100% bounce free. The stretch support of the harness allows you the freedom to move in full speed and in any gnarly condition. The backpack comes with a Heat Resistant 2,0L/ 70 oz Hydration Bladder / Reservoir. The Nordic is also equipped with a thermal function for the hydration bladder itself. During the winter, many athletes heat their hydration before the activity to avoid drinking ice-cold hydration. Therefore, the backpack comes with a hydration bladder that can withstand temperatures up to +140 F (+60 C) and with an outer layer based on the same technology as Thermo Cell on the front of the backpack.
