The 260 ZoneKnit Base Layer Leggings combine heavyweight warmth with breathable performance for serious cold-weather athletes. Engineered with body-mapped merino wool leggings technology, these men’s thermal leggings actively regulate temperature during high-intensity pursuits like skiing, mountaineering, or winter running.
- 100% natural merino wool fabric wicks moisture and resists odors for multi-day wear
- ZoneKnit™ patterning boosts breathability where you need it most
- 29.76″ inseam (size L) with gusseted construction for full mobility
- Flatlock seams minimize chafing under packs or harnesses
Ideal as a standalone performance base layer or under shell pants, these base layer leggings outperform synthetic alternatives in temperature regulation and comfort.

These replaced my synthetic base layers for backcountry skiing. No more clammy feeling during uphill sections, and they stay warm during lift rides. Worth every penny.

After reading reviews of men’s heavyweight base layer leggings, I took a chance on these. The articulated knees make all the difference for snowboarding.

First merino wool leggings I’ve owned that don’t itch. Wore them for a week-long winter camping trip with only one wash – no odors whatsoever.
