The Speedo Mens Hyper Boom Splice Jammer brings back the legendary go-faster Boom Logo stripe from the Speedo design archives, paired with cutting-edge swimwear technology. Its core is the Eco Endurance+ fabric, composed of 53% recycled polyester and 47% PBT, delivering 100% chlorine resistance (rated 5/5) for long-lasting performance session after session. Both yarn components are produced from 100% post-consumer waste such as recycled plastic bottles, making this jammer a sustainable choice for the environmentally conscious swimmer. With a 45 cm leg length, it provides excellent coverage and compression, while the adjustable drawstring waist ensures a secure, personalised fit. The rubberised mesh inner lining with integral support guarantees comfort and modesty during every workout, and the quick-dry technology means you are always ready to go again.
