Exploring above the treeline is a magical feeling. Ancient, picturesque mountains travel as far as the eye can see. It’s the closest thing to what you may call heaven. And the closest thing to heaven on your feet? The Darn Tough Treeline Micro Crew Cushion Socks.

Let’s start with a bit of the technical expertise in these socks. The fabric is midweight, and the fit is supportive but not overly tight or loose. The sock material comprises nearly 58% Merino wool for comfort and odor resistance, with the rest synthetic for added durability. You get all the best aspects of Darn Tough socks and a fantastic color scheme and design.
