Long underwear should be the layer you forget you're wearing. Ours is knit from the same 210gsm merino stretch jersey as our Sport Boxer Brief: 95% merino wool knit in Australia from fine 18.4 micron fiber, with 5% elastane for stretch and recovery.

It's warm enough to wear under ski pants on a January morning, breathable enough that you won't overheat once you start moving, and comfortable enough to wear around camp or the house all evening. The stretch moves with you and keeps the knees and seat from bagging out, and merino's natural odor resistance means it can go more than one day between washes.

Gray is a heathered classic. A smooth wrapped waistband sits flat under a pack's hip belt, and a contoured front panel and slim, tapered leg make it easy to layer under anything.

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

Cut and sewn in the USA.
