Looking for more sustainable and durable skivvies and gave these a try. I haven't had them long, so we'll see how they hold up to multiple washes, but so far quite happy. I am often borderline sm/med and prefer my skivvies to not be snug so went with a med. Fits fine and don't notice them which is the goal!

Wow these merino underwear are amazingly comfortable. They're so breathable and soft, and never feel damp even after running around all day at work. Highly recommend.

This is the second year in a row that I purchase multiple merino wool thongs for the sole purpose of long distance running. I used them for my first marathon and now for my second (and all my runs and workouts in between). They're the best underwear for those long hot, sweaty, or cold, dry days as they're moisture-wicking, they don't slide in the crotch area, don't ride up or down as you run, and you can't feel them while being active like with normal thongs IYKYK it can be very uncomfortable. I put everyone onto these.

I've tried as many merino wool thongs out on the market as I canand Smartwool's tops them all in style, comfort, fit, and especially durability! These don't rip or wear easily, and threads don't fall loose, even after a year of regular use. They're also understatedly sexy! Please make more colors!
