Speedo Men's Swim Jammer HYPER BOOM SPL Black/Grey

Performance that lasts

The Speedo Men's Swim Jammer HYPER BOOM SPL Black/Grey is designed for swimmers who want consistent training and race performance. CREORA® HighClo™ chlorine-resistant fabric helps the jammer retain its compression and shape, even after many hours in the pool. This means a longer lifespan and reliable performance through repeated sets.

Refine your technique

A close, supportive fit helps optimise your body position and leg movement. The HYPER BOOM SPL Black/Grey offers four-way stretch and compression around the hips and thighs, helping to stabilise your position in the water and support a consistent kick. For competitive swimmers, that is the control you need at high intensity.

A secure, supportive fit

The internal drawcord and supportive front modesty panel liner provide a secure, adjustable fit without shifting. With the Speedo Men's Swim Jammer HYPER BOOM SPL Black/Grey, you can perform sprints and dives with confidence, without needing to adjust your swimwear. The fit is designed to provide functional compression without restricting your freedom of movement.

Comfort for long training sessions

Made from Enduraflex with 80% nylon and 20% elastane, the jammer feels smooth against the skin and remains comfortable during long sets. The front liner helps prevent chafing and provides extra coverage during intensive training. This makes the HYPER BOOM SPL Black/Grey suitable for both daily training and race days.

Hydrodynamics and speed

The streamlined shape minimises drag and supports more efficient leg action in the water. The combination of four-way stretch and pilling-resistant materials helps the fabric retain its shape, contributing to faster water flow along your legs. Choose the Speedo Men's Swim Jammer HYPER BOOM SPL Black/Grey if you want to build speed without compromising on comfort.
