WHY MERINO WOOL

INSULATES WHEN WET

Wool has the remarkable ability to absorb up to 30% of its weight in moisture without ever feeling wet or sticky. In the event that it does become wet, wool outperforms cotton and polyester materials by providing superior insulation.

ANTI-MICROBIAL

Merino Wool fibers possess a natural ability to repel bacteria in moisture or sweat, effectively wicking it away. This means you can wear our products without worrying about foot fungus or unpleasant odors.

FIRE RESISTANT

Merino Wool offers excellent insulation against high temperatures and has a natural resistance to catching fire. In the rare event of ignition, it self-extinguishes without melting and adhering to the skin, unlike synthetic fabrics.

MOISTURE WICKING

Merino Wool regulates moisture levels on your skin by absorbing any perspiration or sweat from your body, allowing it to evaporate from the fabric into the surrounding atmosphere.

UV PROTECTION

Leave your sunburn worries behind as you ascend to sunlit peaks. Our lightweight layers provide a UPF rating of 25, while the midweight and expedition options offer an even higher UPF rating of 50+

RENEWABLE

Merino Wool boasts a minimal environmental footprint and seamlessly reintegrates into the natural world. Shear a merino sheep in the morning, and by afternoon, they're happily grazing their way towards renewing next season's wool clip

As soon as I put these on I was in love! I went outside in just these long underwear and wasn’t cold! It was 20 degrees Fahrenheit. I was only out there for a few minutes though. I highly recommend!
