Gear Review: PolarMAX Acclimate Wool Base Layer

Wool has long been recognized for its ability to keep you toasty warm in cold weather conditions. It has been a staple in my snowshoeing wardrobe from the very beginning. 

Wool has good thermal properties and moves moisture away from your skin reasonably well while still in vapor form. The main drawback is once you really start to work hard and generate moisture (i.e. sweat), wool by itself becomes less efficient.

PolarMAX has come up with an excellent solution to this with their Acclimate Wool base layer line. Acclimate Wool is made of 50% Merino Wool, 40% Acclimate Dry performance micro-poly and 10% high performance recycled poly (from plastic pop bottles). This combination works very well to not only keep you warm on really cold days, but also to efficiently transport sweat away from your body. The result is you stay dry during vigorous winter activities. 

I have had the opportunity to test out Acclimate Wool in a variety of conditions recently including cold, wet and windy days. I am pleased that it was up to the task of keeping me warm and very dry. The non-itch, relaxed fit fabric was very comfortable next to my skin, and moved with me instead of against me. Flat stitching at seams also added to the comfort level by reducing any potential friction.

Another feature that is sure to be met with approval from your workout partner or spouse, is that of scent prevention properties within Acclimate Dry. PolarMAX developed this anti-microbial, anti-odor process to meet the demands of the U.S. Military. This technology stops odor before it starts by killing the bacteria that causes odor. Also, with the assurance of not smelling, the zip mock top looks great and could easily be worn to dinner or the pub after your snowshoe outing.

Acclimate Wool is available in a crew top, zip mock and pants.
