When the temperature drops, this is the first layer on. Our Merino Wool Long Underwear in Indigo is knit from a 210gsm merino jersey with 5% elastane, made in Australia from fine 18.4 micron wool, then cut and sewn in the USA.

Merino holds warmth when you stop and breathes when you're working, so it handles the stop and go of nordic and alpine skiing, winter hiking, and long days outside in the cold. It's versatile enough to reach for well beyond the deep of winter, from cool fall mornings to spring skiing, and it resists odor naturally on multi-day trips.

Indigo is a deep navy that pairs with everything. The slim, tapered fit layers cleanly under ski pants or hiking pants, and a wrapped waistband stays flat and comfortable all day.

Returns: Only unopened, unworn long underwear can be returned. Items that have been opened cannot be returned.
