For guys who want comfort and performance in their underwear, these Smartwool boxer briefs are a game-changer. Made from 100% merino wool, they're naturally moisture-wicking, odor-resistant, and temperature-regulating. The wind-resistant front panel (with a 1 CFM rating) gives you extra protection during outdoor activities, and the UPF 39 shields you from the sun. Flatlock seams mean no chafing, and the smooth elastic waistband stays put without digging in. They're mid-rise and come in sizes from Small to XX-Large – check the waist/hip measurements to find your fit. Machine washable and dryer-friendly, so they're easy to care for. Perfect for hiking, skiing, running, or just everyday wear when you want something soft, breathable, and durable.
