Triathlon is one of the UK's fastest growing sports but it is essential, when competing, to have the correct clothing and equipment. With performance enhancing fabrics that accelerate blood flow to get more oxygen to the muscles, a Trisuit is essential as it minimises drag in the water and provides comfort when on the bike and running. A wide range of accessories are also available, including swim caps, race belts for hydration and gels, headwear and sunglasses. Sizes may vary according to brands. We suggest that you check your size with our relevant size guides.
