The FINA (International Swimming Federation) approved Speedo Boy's Fastskin Junior Endurance+ High Waisted Jammer is part of Speedo's medal-winning Fastskin collection. Built for competing, its low-profile flatlock seams reduce irritation, and its 4-way stretch technology ensures comfort, allowing you to focus on your race. Plus, a unique asymmetric leg means you'll stand out on the blocks. It’s designed to last and withstand everything your race day swim sessions throw at it.
The finest lightweight fabrics and supportive compression are the perfect stars of the revolutionary Speedo Fastskin LZR Pure Valor Jammer. Be focusing on moderate compression in key areas, both lactic acid and fatigue are kept at bay, even when your muscles feel like they can’t go on anymore, and there’s still plenty of free movement to help you make every kick count in the water. Not only that, but the levels of hydrodynamics here are exceptional with bonded seams for reduced drag and even less painful rubbing against the skin. Finally, the waistband is brilliantly constructed to prevent water ingress once and for all.
