Mountain Hardwear

Butter Up Slim Pant - Men's

What Our Gearhead® Experts Are Saying:

"I reach for these when I want a lightweight layer that still adds real warmth. The brushed fabric feels super soft but still wicks moisture when you’re moving. They’re great for cold morning runs, and the slim fit makes them easy to layer under ski pants when the temperatures really drop."

Cold-weather adventures call for layers that keep us warm without slowing us down, and the Mountain Hardwear Butter Up Slim Pant fits the bill perfectly. Whether we’re heading out for frosty trail runs, warming up before a day on the slopes, or adding an extra layer beneath our ski shell, these pants deliver soft comfort that keeps us moving confidently through chilly conditions.

The brushed polyester knit feels smooth against the skin while providing just the right amount of warmth for active pursuits. Built-in stretch gives us unrestricted mobility on climbs, strides, and descents, while moisture-wicking performance helps regulate temperature when our pace picks up. An elastic waistband with an external drawcord keeps the fit secure, and the slim silhouette layers easily under snow pants or outerwear when winter conditions demand extra insulation.
