lightweight and surprisingly durable for it being 100% merino wool

Great underwear. I’ve been wearing merino wool underwear for over 20 years, and most of it is from icebreaker. The benefits of wool are huge. This is especially true for clothing that can get pretty funky in the field, traveling, working out, etc. Wool greatly reduces the funk. If I were to complain about anything, it would be the nylon in the wool. I would prefer a higher percentage of wool.

Favorite Underwear

I've been sold on the Icebreaker boxer briefs for years! Keep the stink away, fit great, and good looking colorways. Ditch your cotton and go merino.

Fantastic Underwear For All Season

fits well, with good stretch, feels almost like it's not there incredibly comfortable. I went from 75°f weather on runs to 10° hiking in the mountains with a -10 wind-chill. they held up great for both. the only negative is during hight intensity runs (2 -5 miles in 13-35 minutes) it can ride up a bit otherwise it's solid for more casual runs (6miles per hour)

Soft And Breathable

Bought several pairs of these. I have used them on multi day adventures and for work. I enjoy the length of these and they don’t ride up like other underwear. Will purchase a few more in the future.
