Speedo Mens Brief
Train Hard. Last Longer.
The Speedo Solid Boom Brief is a no-nonsense training brief built for swimmers who put in the laps. Constructed from Speedo's Endurance Pro fabric — 100% recycled yarns with four-way stretch — it resists chlorine and pilling so it holds its shape and colour through the toughest training blocks.
An internal drawcord keeps the fit locked in, so you can focus on your stroke, not your swimwear.
