Men's Gray Underwear

For workouts, boxer briefs and trunks offer compressive support and stay secure during movement. Models like the XYXX boxer briefs use snug spandex/nylon blends and longer leg options to prevent chafing and bunching.

Lightweight natural fibers such as cotton, linen, and silk promote breathability for hot, humid days. Tommy John briefs also come in airy constructions, while Tencel and modal blends wick moisture if you prefer synthetic performance.

Reach for long underwear when you need full thermal coverage for cold-weather activities. Look for layered construction and knee-length or full-length options that trap heat beneath outer pants.

Thongs and g-strings give the cleanest silhouette under tight pants thanks to their narrow rear and minimal fabric. Trunks like the Gruff Pup models or smooth spandex/nylon g-strings reduce visible lines while still offering enough support for light activity.

Size boxer briefs and trunks so the waistband sits snugly without digging and the leg hits mid-thigh to prevent riding up. Compressive blends and popular cuts like XYXX's snug-fit boxer briefs tend to resist bunching during long days.
