Serious swimmers, these 3asyglide jammer shorts are built for performance in the pool! Made from high-quality 53% polyester and 47% PBT fabric that's actually manufactured in Italy, these shorts feature 4-way stretch that moves with your body without restricting your stroke. The chlorine-resistant material means they'll last through countless training sessions without fading or breaking down. With UPF 50+ protection, they've got you covered even during outdoor swims, and the quick-drying fabric means you're not sitting around wet after practice. The flat-locked seams are a game-changer - they lay flat against your skin so there's no chafing during those long training sessions. The drawstring waist with flat cord ensures a secure fit without digging in, and the front lining provides that extra comfort and coverage. Whether you're competing in meets, doing laps for exercise, or just want performance swimwear that actually lasts, these jammers deliver professional quality without the crazy price tag. The black color looks sharp and won't show wear easily. Rinsing with clean water after each use will keep them in great condition season after season. Your swimming performance is about to get a serious upgrade with these quality jammers!
