The durable construction incorporates a 75 denier recycled polyester fabric with a PFC-free, water-repellent finish. The kick patches use 210 denier recycled nylon laminate for extra protection against sharp rocks and crampon edges. Waterproof and windproof GORE-TEX keeps the elements at bay. The expanded polyethylene (ePE) membrane is PFC-free, bluesign approved and has a reduced carbon footprint for outstanding eco performance. The feature-rich design includes two-way side zips that fully separate, making them easy to put on without needing to take boots off. You can cinch-in the waist using the internal adjusters for a more secure fit. Zipped handwarmer pockets offer comfort and storage, protected by waterproof zips. An embedded RECCO reflector aids detection in search and rescue emergencies for extra safety. Comfortable whether hiking or roped up, the articulated patterning maintains mobility when wearing a harness. Finished with a double-cuff design incorporating an adjustable internal gaiter, you can pair the Triolet Pants with a range of mountain boots.
