The Alpine Onset Merino 150 Plus Bottoms are a soft, breathable, moisture-wicking bottom designed for use as part of a strategic layering system for active outdoor wear while skiing, snowboarding, climbing, hiking, and more.
Crafted with a non-mulesed merino wool blend, this lightweight, breathable, wicking, and quick-drying base layer ensures comfort while stretching and moving with the body for unrestricted movement and a natural range of motion. The flat-seam construction delivers chafe-free performance, while the elastic logo waistband provides low-profile comfort that perfectly layers under a shell. And when the need arises to strip down to the bare minimum, the UPF 30 rating shields from the sun's UV rays.
When layering up for a long day in the mountains or a chilly morning workout, the Alpine Onset Merino 150 Bottoms are an ideal addition to the perfect layering kit.
