The Ortovox 230 Competition Long-Sleeve Top thrives as we reach higher elevations and trek deeper into the backcountry. The body-mapped merino wool provides warmth everywhere we need it, while the mesh structure ensures that we are able to dump heat as we work our way up the skin track. The quick-drying properties of Merino wool keep us feeling fresh, and the added durability of the nylon weave ensures we can enjoy reliable warmth and comfort for many tours to come.
