Unconditionally Guaranteed For Life
All of the Darn Tough socks are knit with small needles on fine gauge knitting machines, and this company only uses 100% Merino wool. The stitching ends up very dense without the bulk, resulting in a better fit. The better the sock fits, the longer it will last. The socks are reinforced on the outside and inside with nylon and lycra for added comfort and durability. This company has been making great socks like these for generations, in Vermont, USA.
