Featuring Speedo's new signature print Boom, these Jammers made from our Endurance®+ fabric, are perfect for fitness training and offers a comfortable fit thanks to its four way stretch technology. The black and blue Boom Splice Jammer is designed to hug the contours of your body to create a hydrodynamic profile in the water. They may feel soft when they're on, but they're reassuringly secure too with their drawstring waist.
Our most durable fabric, Endurance+ uses a blend of PBT and Polyester fibres to provide 100% chlorine resistance, with a higher level of snag and fade protection than traditional swim fabrics.
Featuring multi-directional stretch fabric for improved softness, our Endurance+ fabric offers excellent comfort and fit properties, so you can simply focus on your swim.
