Smartwool Merino Sport brief

The Men's Merino Sport Brief takes all of the tech you love from the Merino boxer briefs—a lightweight feel, breathability, anti-stink Merino—and adds a looser fit.
With a fully functional fly and a wide, Merino-lined elastic waistband, you'll experience maximum comfort all day long.
No matter if you're hitting the trail for a three-day camping trip or trying new sports, the Men's Merino Sport brief brings you the performance and comfort you can expect from our ultra-soft, responsibly sourced Merino wool.
