Thru-hikers logging hundreds of miles on the Appalachian and Pacific Crest Trail swear by Darn Tough's incredibly sturdy socks. While you're like not going to be trekking hundreds of miles on your trip, the same properties that make these socks great on the trail make them ideal for traveling. Merino wool socks are soft, stretchy, naturally sweat-wicking, and odor-resistant, keeping your feet comfortable under all conditions-even when they're wet. What sold me on Darn Tough socks' is they're unconditional lifetime guarantee, "If our socks are not the most comfortable, durable and best fitting socks you have ever owned, return them for another pair, or your money back. No strings. No conditions. For life." While I have not owned my for life, after a few years of hardcore use they still preform like new.
