Flaws but not dealbreakers: The 150’s 5.75-inch inseam is ample and provides coverage to more common chafing areas, but it’s not as long as some of the other options on this list. A little secret to running success? A good foundation. And no, we’re not talking about running shoes. We’re talking about underwear.

Why they’re great: You just can’t beat merino wool underwear when it comes to comfort and breathability. Smartwool gets this, as evidenced by its super cozy, anti-chafing Merino 150 Boxer Brief. 88% merino wool and 12% recycled nylon join forces to provide outstanding breathability and natural odor-fighting properties. This is another highly technical pair of boxer briefs that will serve you well on your daily run, while running errands on a hot summer day, or during your next epic outdoor adventure. Yes, underwear does help prevent chafing. These are specially designed garments that act as thigh bands, which prevent thigh rubs and the friction they cause. The size is accurate. In fact for an ‘XL’ size, the firm fit and style feel like an ‘L’ or even an ‘M’. This means the nylon and spandex material blend offers compression. For anti-chafing underwear, these slip shorts are shapewear as well. I like underwear that really does its job, you know? It won’t shrink or the color won’t fade. No matter how many times I wash it. And if you’re like me, and you sweat a lot in general, you need that assurance.

Sure, we love the idea of running without underwear—the ease, the breathability, the joyful freedom of springing lightly into motion without excess fabric to hinder our movement. But the sweaty, skin-chafing reality? Not always as good as it sounds. Deodorant acts as an antiperspirant or lubricant to avoid sweat-induced irritation and keeps the skin smooth and dry and thus, prevents chafing. What about the waistband though? Is it tight enough and does the tightness press into the stomach? This brand promises a stress-free experience. The waistband is secure, firm, and durable. It doesn’t roll up or slide down. Look for seam-free and tag-free underwear so you can rest assured that you won’t experience unexpected chafing or itching while running. Underwear that allows for four-way movement is also a good option, so you’re wearing a garment that moves with and not against you. How We Selected
