The Trilogy collection gets its name from the solo peak bagging winter ramble of the Cervin, Eiger and Jorasses' North faces by Eric Escoffier and Christophe Profit. With this epic challenge, these two mountaineers from the Millet team set the ground of modern mountaineering in the 80s: Take the essential with you and carry the lightest weight on your ascent. Trace routes. Climb quickly and steadily. The expert's advice: The Trilogy Storm pant has got you covered: The shell's inner face is brushed for added warmth and comfort, Cordura reinforcement at the bottom of the legs provides enhanced abrasion resistance, lateral vents, cargo pockets and box pleats for a perfect fit over your boots.
