The FXR Men's Atmosphere Boxer Briefs deliver lightweight comfort and moisture-managing performance for active days and cold-weather layering. Built from a 140gsm 88% polyester / 12% spandex knit, they provide flexible stretch and a close, comfortable fit. A moisture-wicking and anti-microbial finish helps manage perspiration and maintain freshness during extended wear, while flat-lock seams reduce bulk and irritation against the skin. A jacquard elastic waistband provides a secure fit, and screen printed logos complete the streamlined design.
