Men's Alpine Onset Merino 150 Bottoms

About this find

The Men's Alpine Onset Merino 150 Bottoms from Outdoor Research are a lightweight base layer made from a soft, non-mulesed merino wool blend. The fabric is breathable, moisture-wicking and quick-drying, and it stretches and moves with your body for a natural range of motion. They are designed for active days outdoors, including skiing, snowboarding, climbing and hiking.

Flat-seam construction delivers chafe-free performance, which matters when you are lifting your knees on a steep climb or carving turns all day. The elastic waistband carries the Outdoor Research logo and has a low profile, so it layers neatly under a shell and mid-layers. These bottoms also have a UPF 30 rating, so they shield your skin from the sun's UV rays when you strip down to the bare minimum.

Think of them as the first piece in a layering system. Pair them with a shell and mid-layers for a long day in the mountains, or wear them on their own for a chilly morning workout. If you plan to wear them under shell pants, pick a pair that leaves a little room so the base layer can move freely with you. The merino blend and stretch make them a steady foundation, whatever the day throws at you.
