What reviewers say
Treeline Review calls them one of its favorite pieces of gear, based on thousands of trail miles from freezing temps to over 100°F; the reviewer usually gets about 600 miles a pair before visible wear. Reviewers like the snug fit that doesn't slip or bunch, the moisture handling and odor resistance, and the lifetime warranty. The main knocks are the upfront price and that they are not as soft as alpaca blends. People with wide feet or calves may find the fit tight. Compared to Smartwool, Treeline notes Darn Tough uses more wool and has the longer warranty.
Good
- Very durable
- Stays in place without bunching
- Comfortable across a wide temperature range
- Lifetime guarantee
- Made in the USA
Not so good
- Expensive per pair
- Snug fit may not suit wide feet or calves
- Not as soft as some alpaca socks
Who it's for
Hikers and backpackers who want one sock that lasts years and works most of the year. Skip them if you have wide feet or calves, or if cheap socks already work for you.
