Our Men's Brief takes all of the tech you love from our Merino boxer briefs—a lightweight feel, breathability, anti-stink Merino—and adds a looser fit. With the 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, our Men's Brief brings you the performance and comfort you can expect from our ultra-soft, responsibly sourced Merino wool.
