SBD sportswear is the training side of the range: what you wear to the gym rather than onto the platform. It covers training t-shirts and long sleeves in men's and women's fits, oversized tees, women's crop tops, training shorts, and the hoodies and sweatshirts, in the Classic black and red plus whichever limited edition colourways are current.
The training tees are cut looser than the competition tee and made for sweat and washing, not for a referee's inspection, so they are the right choice for everyday sessions. Sizing follows the SBD apparel size charts on each product page; if you sit between sizes on the oversized tee, go down rather than up, as the cut is generous.
