- Adjustable stretch waistband
- Gusseted seat for full range of motion

Materials & Feel
The brushed stretch knit delivers the signature buttery hand-feel with enough compression-free stretch for high steps, lunges, and crampon stride.
Fit & Sizing
The Butter Up runs true to size with a slim athletic cut; the adjustable waistband dials in fit without a drawcord bulge under harnesses.
Good for Cold Weather Running?
Yes. The midweight stretch knit insulates on cold runs while staying breathable enough that you won't overheat – a top pick for winter running tights alternatives with pockets-free simplicity.
Winter Hiking & Cross-Country Skiing
Warm enough for winter hikes when layered under shell pants, and popular as a cross-country ski base layer thanks to the gusseted seat and articulated movement.
Climbing Gym to Alpine
Slim enough under a shell, stretchy enough to send V6 – this pant holds its own as a standalone or as the warm mid layer in your alpine kit.
