Hard training sessions and long-distance skis ask a pant to block wind and stay breathable, and the Swix Quantum Windstopper Pant does both with a lightweight GORE-TEX Infinium Windstopper softshell. Articulated knees and elastic panels let this windproof cross-country ski pant follow every stride, while an elastic waistband with an internal drawcord keeps the fit snug. What Our Gearhead(R) Experts Are Saying:"On hard interval days, I opened the leg zippers once the effort climbed, and the heat building around my legs vented right out. I kept them closed for the warm-up and cooldown, so one pair covered the whole session."
