Premium 100% merino wool base layer long sleeve. This mid weight wool shirt is perfect for all outdoor activities year around and also suitable for everyday use because of its clean design. It is made in our pureUll wool, a premium 100% merino quality and we use it because of the natural properties the wool offer: It is temperature-regulating, retains body heat while transporting moisture away, effectively keeping you warm, even when wet, and is also natural odor-resistant. The pureUll is an all-natural material made in 100% ultra-fine 18. 5 wool micron that offers the perfect balance between performance and non-itching next-to-skin softness. It's a medium-weight (180gr/sqm) single jersey knit which is highly durable for its kind in terms of both wear and tear, pilling, abrasion, and snagging. The wool is RWS certified, and it’s sewn and knitted in Europe. This shirt has a regular fit with articulated arms for full mobility.
