Why do swim coaches recommend jammers?
Jammers are designed for swim training. They stay secure, reduce drag in the water and allow boys to move freely during lessons, laps and squad sessions.

Regular swimwear is usually made for occasional beach or holiday use. Training swimwear is designed for frequent pool lessons, using chlorine-resistant fabric that helps maintain shape, comfort and coverage over time.
