Darn Tough Fastpack Micro Crew Lightweight Hiking Sock 25/26

This Darn Tough sock is a hiking sock in a lightweight knit. Darn Tough knits its socks from merino wool blends at its mills in Vermont, using its True Seamless toe construction for a smooth feel.

The trade-off with sock weight is warmth and cushion against fit and breathability. Lighter socks run cooler and fit closer, while heavier socks add padding and warmth for cold days and big loads.

It is for hikers and backpackers who want a sock that manages moisture and regulates temperature on long days, with a performance fit that keeps it from slipping or bunching in the boot.

Every Darn Tough sock is unconditionally guaranteed for life: if they ever wear out, Darn Tough will replace them. Check the size chart against your shoe size.

We think Darn Tough hiking socks are the best friend your feet can have on the Long Trail, and they are knit right here in Vermont.
