Mens Boxer Briefs - MicroModal Long Leg Underwear | Debriefs

Boxer briefs combine the close-fitting support of briefs with the thigh coverage of boxers. Debriefs boxer briefs have a 9 cm inseam, a 3D contoured pouch and a close fit through the waist and legs. This longer-leg style is designed for support, movement and protection from thigh-to-thigh rubbing.

Debriefs boxer briefs have a 9 cm inseam. The leg covers more of the upper inner thigh than the 5 cm trunks, which makes boxer briefs a better starting point if you have larger thighs, experience chafing or prefer more coverage.

Choose boxer briefs if you want more thigh coverage, your thighs rub or you need underwear for active days. Their longer 9 cm legs are designed to stay in place and reduce skin-on-skin contact. Choose trunks if you prefer a shorter leg or want less fabric under fitted trousers or shorts.

Debriefs boxer briefs are designed to reduce chafing. The 9 cm legs cover the upper inner thighs to reduce skin-on-skin rubbing, while the breathable MicroModal blend manages moisture. Flat-lock seams also avoid the bulky raised stitching that can create extra friction during long or active days.

Debriefs boxer briefs are designed to stay in place without riding up or bunching. Their form-fitting 9 cm leg design helps each leg sit below the widest part of the upper thigh. Reinforced leg hems add structure at each opening to help the legs hold their position, while four-way stretch lets the fabric move with you instead of gathering. The right size helps the legs and waistband sit as intended.

Yes. The longer legs help protect the inner thighs, while the four-way stretch fabric moves with the body. LENZING MicroModal is breathable and moisture-wicking, making the boxer briefs a strong choice for running, gym sessions, physical work, long flights and other days when heat, sweat and rubbing can build up.

Debriefs boxer briefs use a 230 GSM blend of 94% genuine LENZING MicroModal and 6% elastane. LENZING MicroModal is three times softer than cotton. The finished fabric feels lightweight against the skin while remaining high quality, durable, breathable, moisture-wicking and flexible in four directions. The boxer briefs are made in Turkey by a GOTS-certified manufacturer.

Yes. The MicroModal blend absorbs and releases moisture to help reduce the hot, damp feeling that can develop in heavier cotton underwear. The fabric remains breathable even with the longer 9 cm leg, making these boxer briefs suitable for warm weather, active days and men who tend to sweat.

The horizontal fly gives access from above instead of through a vertical side opening. Around it, the 3D contoured pouch follows the body's shape to provide room and support. The design works for left-handed and right-handed wearers and keeps the pouch supportive without making access awkward.

Measure your waist and match it to the Debriefs size chart. Do not assume the same labelled size will fit identically across different brands. If you are between two Debriefs sizes, choose the larger size. The waistband should lie flat and the leg openings should feel secure without restricting movement.
