By fusing together low-micron merino wool and polypropylene fibers, you get an incredibly strong yarn that allows a middleweight to act like a heavyweight in both warm and cold climates. They’re strong, wicking, odor and blister resistant, breathable, quick drying… and they immediately recover in the wash. Made in the USA.

This burly, fitted sock gives you protective padding in just the right thicknesses, where you need it the most. The reinforced toes, heel and shin pads allow you to lace tightly with no pressure and the merino wool fibers breathe, insulate when damp, and are virtually itch free. Made in the USA.
