Men’s Performance Fit Merino Wool Boxer Briefs

Restock coming this fall - sign up for restock updates to be the first to hear.

Our Performance Fit Boxer Briefs feature a super soft fabric, a horizontal fly and fixed vertical seams for a supportive fit, making them a great Merino wool underwear option for any activity. Many performance underwear styles eliminate the fly for better support, but our Performance Fit Boxer Briefs have the best of both worlds — the convenience of a fly plus full lateral support.

These Merino wool boxer briefs are soft against your skin but still durable thanks to our corespun (m)Force™ Technology. A hint of spandex provides long-lasting stretch and recovery. They have all the benefits of Merino wool: they resist odor, dry quickly, regulate temperature, breathe well and wick moisture. Like all of our underwear, they’re free of chemicals and microplastics, so they’re good for you and for the environment.
