Speedo Youth Boys Boomstar Splice 6.5cm Brief

Sleek-look briefs with iconic Speedo branding. Sharing the same great fit as our Essentials swimwear, our 6.5cm Splice Brief features Speedo’s new heritage-inpired BoomStar print. Lined at the front for comfort and modesty, they include an internal drawcord to allow young swimmers to adjust the fit. Soft, stretchy fabric makes them ideal for regular swimming, while our shape-retaining Endurance10 fabric with Creora HighClo ensures they fit like new for longer.
