Tough, technical, and providing the needed level of comfort in the bitter cold, the Rab Photon Pants are synthetic insulated pants ideal for mountain guides and mountaineers alike. Made from Stratus recycled insulation to keep you warm even in the extreme cold, these pants feature a tough Pertex Quantum exterior with additional Pertex Shield 2.5 layer reinforcement patches on the high-wear areas like the seat, knees, and kick patches. Full-length side zips make these a breeze to take on and off during changing conditions, transitions, or your ride to have an apres-ski beer when the heat doesn't work. Two YKK zipped hand warmer pockets, a zipped fly opening, and a wide waistband keep things thoughtfully minimal. The large reflective logo keeps you bright in the night, with the stuff sack allowing these to be easily packed away for next time (like 5 minutes from now). The Rab Photon Pants come with a dangerous level of comfort, easy use, and utility for expeditionary climbs, so much so that you might find yourself walking around the house in them. Yet they remain always ready for the next big climb.
