Fastpacking, for the uninitiated, is trail running combined with camping. You’re outside, you’re moving fast and you’re packing only the bare essentials, which means you might just be bringing a single pair of socks. Luckily these lightweight cushioned socks from Darn Tough are ready to go all the way, with nylon and merino wool for moisture wicking and antimicrobial properties that mean they can go a few wearings between washes and still stay fresh. With their colorful stripes and micro crew length, they also look great peeking over the tops of your hiking boots. Let’s hit the trail!
