flag trunks

Many flag trunks use a 2-in-1 design with a soft compression liner plus an outer trunk. Some adult briefs include a front lining. Liners are described as providing added comfort and protection during activity.

Several listings explicitly specify UPF 50+ sun protection. That rating appears in short attribute bullets and in descriptions for youth/hybrid and adult options.

Closures range from full elastic waistbands and pull-on styles to front drawstring waists. Multiple listings note adjustable drawstrings for a customized fit.

Sellers highlight flat-locked or flat seams to reduce chafing and compression liners that help prevent sand friction and skin itching.

Listings commonly use recycled polyester/PBT blends, polyester, polyester blended with spandex, and nylon.

Many adult listings offer US sizes S–XXL; one brief lists numeric sizes (26–40). Infant and youth options are also available.

Many listings emphasize quick-dry fabrics and 2-in-1 compression liners for flexibility and reduced irritation. One listing is labeled chlorine-resistant, and several explicitly note suitability for swimming and surfing.

Coverage is listed as Medium or Classic across listings. Only one adult trunk specifies a 5.5" inseam (above the knee); most listings do not provide clear inseam measurements.
