Choose the right swimwear for your type of swimming - from training to race day

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 white and red 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.

Features and Benefits

  • Drawstring Waist - For enhanced fit and security
  • Integral support for enhanced comfort
  • 100% chlorine resistant, so your swimsuit won’t degrade in the swimming pool
  • Freedom to move – 4 way stretch technology for comfort and softness
  • Endurance®+ fabric retains its shape and resists fading longer than any other swim material.


Designed to last longer

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.

Lincoln Swimmer
Durable, I find these jammers will wear very well and don't go loose or thin like some other bands.
Nice looking ( if you have the physique).
Sizing is a little on the small side. I order one side larger than I usually buy.
