The Mountain Hardwear™ Butter Up™ Slim Pants are alpine-inspired active slim pants that can be worn alone or as a base layer. These mid-rise pants feature UPF 50 protection that filters harsh UV rays while the easy pull-on elasticized waistband ensures a perfect fit. The external drawcord at the waist offers adjustability. Crafted from brushed jersey knit fabric that wicks away moisture, these skinny-leg pants are perfect for your outdoor rides and adventures.
