These undies are surprisingly comfortable!
Decent in summer, but I’m looking forward to wearing them more often in colder seasons 😉

Thrilled to have 100% merino wool briefs that fit and are comfortable. I am 5'11 and 170 pounds, and the medium is perfect for me. The briefs have nice give and do not smother you, but they also do not become super loose fitting after a few days on the trail. Super comfy fabric against your skin, and you barely know they are there. Plus the fly is a nice addition, as some briefs do not have a fly. Highly recommend!

Miharo Wuru!

Wonderful fabric & fit. Excellent for everything: ski, hike, work, sleep. Wide waist band is the way.
