  • WARM INSULATION: The targeted insulation and ventilation in the Men’s Merino 150 Pattern Base Layer Bottoms allow you to stay comfortable while you’re out working up a sweat.
  • COMFORTABLE FIT: These bottoms are made with an interlock knit for enhanced comfort, breathability, thermoregulation, and odor resistance with a Merino-covered waistband and traditional fly design, allowing you to wear them all day long without any discomfort.
  • DURABLE WEAR: The flatlock seam construction of these bottoms is specially designed to minimize chafing, making these boxer briefs perfect to wear underneath snow pants during a long day of skiing!
  • MERINO 150: This heavier, soft, 87% Merino wool and 13% Nylon fabric offers breathable warmth, moves sweat away from the body, odor control, thermoregulation, and provides next-to-skin comfort in colder weather conditions.
  • CARE INSTRUCTIONS: Comprised of 87% Merino Wool and 13% Nylon, the Men’s Merino 150 Pattern Base Layer Bottoms should be machine washed in warm water on a gentle cycle and tumble dried on low. Cool iron and dry clean as needed, but do not bleach these bottoms.

The Smartwool community is a collection of people who believe that time outside is valuable, restorative, and essential for everyone.When Smartwool started making socks back in 1994, their founders simply wanted to be able to ski longer without getting cold toes. That’s when they discovered the benefits of Merino wool as a performance fabric. It was soft (softer than any wool they had every felt), moisture-wicking, thermoregulating (warm when it’s cold, and cool when it’s warm), sustainable, and odor-neutralizing- helping to keep feet dry, comfortable, and warm for longer than the synthetic socks they were wearing at the time. It worked so well, in fact, that Smartwool uses it in almost every single item they make.

Smartwool was the first outdoor company to make performance Merino wool ski socks- revolutionizing the category and forever changing the way outdoor enthusiasts viewed their feet.

Smartwool’s whole brand was built on the desire to be comfortable on outdoor adventures-we wanted to go farther and experience more. And that drive continues to fuel everything Smartwool does. From their Merino wool supply chain to the Smartwool advocacy program to how they design their socks and apparel, Smartwool exists to help you play, love, and laugh in the great outdoors as often as you would like.

    Smartwool brand never disappointed me and I bough many pieces before. Feels like a second skin super comfortable !!!

    But over priced.

    This was a gift for my son who requested this brand. He was very happy to receive it.

    Exactly what I expected. Good fit, comfortable.
