What Our Gearhead(R) Experts Are Saying: "These are my go-to for touring and shoulder-season missions. Super breathable, super soft, and they layer perfectly with ski boots and socks."Built for aerobic days in cool conditions, the Men's Lightweight 3/4 Bottom keeps us comfortable from bootpack to summit thanks to a featherlight, breathable blend of rayon and Merino wool. This temperature-regulating combo excels at moving moisture and fighting odors, while a touch of elastane ensures a mobile, second-skin fit that doesn't bunch under layers. The 3/4 cut eliminates overlap with ski boots or high-cuff socks, making it the ideal base for shoulder-season tours, Nordic laps, or high-output winter workouts.
