Darn Tough Men’s Fastpack Micro Crew Hiking Sock | VT Made
Lightweight feel. Heavyweight performance.
Built for vertical miles and long trail days, the Fastpack Micro Crew delivers breathable comfort and dialed-in support without unnecessary bulk. Knit in Vermont from premium merino wool, this lightweight hiking sock keeps feet dry, cool, and blister-free from trailhead to summit.
Engineered with fatigue-relieving arch support, extended Achilles cushioning, and targeted breathability across the top of the foot, Fastpack is designed to move. The sleek striped design adds just enough style to stand out — without trying too hard.
And like every pair of Darn Tough, it’s unconditionally guaranteed for life.
