A quintessential alpine identity plus the efficiency of a lightweight, compact, clean-cut technical style, this is THE pacesetting protective jacket for mountaineering, epitomizing MILLET's expertise. In committing situations, it offers powerful GORE-TEX® PRO® Pegase 3L, which acts as a total barrier against the most abrasive surfaces and for protection in the most extreme weather conditions, in a super-light design. With a waffled interior for greater robustness, and high breathability, the K GTX PRO JKT plays an active role in the challenge of the ascent, reinforced by tone-on-tone CORDURA® shoulders to durably withstand repeated rubbing by backpack shoulder straps and ropes. Its sport ergonomics erase all mobility constraints so you stay focused on essentials. For performance, it delivers technical functionality: 3 pockets, vents, technical hood compatible with mountaineering helmet, and double-slider main zip for easy harness access.
