MOMENTUM Innerwear Jammer Underwear - Black

Classic black jammer for everyday active wear. The MOMENTUM Innerwear Jammer - Black (MCMI3357BT) by Private Structure offers the perfect balance of athletic function and daily comfort. Its long-leg "jammer" cut extends down the thigh to provide superior coverage, effectively preventing chafing and keeping the fabric in place during movement.

Soft stretch cotton for all-day freshness. Designed as part of the Innerwear collection, this jammer is made from a high-quality blend of 95% cotton and 5% spandex. This fabric combination ensures the natural softness and breathability of cotton while offering enough stretch to move seamlessly with your body, making it ideal for both active days and relaxed wear.

Sleek design with reliable support. The timeless black color is finished with a sporty branded waistband that provides a secure, comfortable fit without digging in. The engineered contoured pouch offers ample room and support, creating a defined, masculine silhouette and keeping you comfortable all day long.
