The Rock & Ice is the warmest, most advanced parka on the market. Nine years of experimentation and constant feedback from climbers have gone into making the Rock & Ice Parka, designed to keep even the most fatigued body warm in brutally cold conditions. Filled with over 21.4 ounces of 750+ fill down, it is baffled and differentially cut throughout the parka and hood. The permanently attached hood overlaps the collar and closes over the lower face. As a custom option, this parka can be made with a "tunnel style" hood with the brim extended completely around the sides (increasing wind protection to the face). The Rock & Ice features a double zipper front closure with a down overflap and reinforced shoulders, back and elbows. Three piece articulated elbows and two piece set-in sleeves give increased arm and shoulder movement. Construction includes an elastic powder skirt and cuffs, velcro wrist closures, mitt clips and a waist drawstring. Two large external cargo pockets, two inside chest pockets sized for one-liter bottles and net cargo pockets below the powder skirt provide space for spare gloves and food. With its 100% windproof PTFE-Lite or PTFE-Max shell, the Rock & Ice is the ultimate expedition parka.
