Layering icebreaker merino wool clothing and underwear is your secret to changing climates. A single icebreaker layer protects you from the sun and still keeps you warm at night.
Layer 2 or 3 Icebreaker clothing pieces, and you have a lightweight system that not only moves with you as if it were one garment, but breathes in its entirety, just as if it was on a merino at 7,000 feet.
Icebreaker Merino wool underwear and clothing shares the same building blocks as human skin - keratin. This is one of the reasons why icebreaker feels so good against your skin. It's the keratin in merino wool that also makes your icebreaker naturally fire resistant.
