Product Overview

What makes this merino package so unique is that it is a dual layer material, not a blend. Using a super-fine polyester on the interior and merino wool layer on the exterior, this material combo does some very incredible things. When the user sweats or gets wet the poly layer will quickly wick away moisture from the body and transfer it to the absorbent wool layer. Once the moisture permeates into the wool layer it allows the poly to dry very quickly which helps avoid the typical stink you find with other synthetic layers, additionally wool is naturally antimicrobial which makes it incredibly difficult for the garment to produce bacteria that causes odors in all synthetic base layers. Furthermore, once the moisture is absorbed into the wool layer it will keep the user insulated and warm even when wet. 

Made in the USA!
