Speedo Hyperspark Lycra Jammer

Speedo's Hyperspark Jammer cuts an above-the-knee racing shape from a chlorine-resistant stretch fabric, with flatlock seams holding it flat against the body. Compression runs firm through the core and thighs, while vertical stretch keeps the legs free through each kick. Machine washable, its close fit stays secure through movement. **Product Highlights** • Flatlock stitching that minimises chafing and keeps the suit stable in water • Targeted core and thigh compression for added stability off starts and turns • Lycra Xtra Life elastane holds shape against chlorine exposure over repeated wear • Limited horizontal stretch delivers leg-muscle compression without restricting range of motion • Made with 79% recycled fabric • World Aquatics certified for officially sanctioned races **Best For** • Club and squad swimmers moving up to championship-level competition • Multi-event meets where comfort matters across heats and finals • Racers chasing sharper push-offs on tumble turns and explosive block starts • Swimmers between sizes preferring a less firm hold around hips and thighs • Gifting to a competitive swimmer ahead of a key season
