Different by Design – Made from the ground up from our own research and development the performance roller is an advanced high-density foam roller made for serious sports people and athletes. No messing around this product is for people that train hard and know how important it is to keep their muscles loose, fascia treated and prevent any injuries. Made from a high-density foam with a density level of 50, it provides a firmer than normal massage. We wrapped this around an EVA tube for extra tensile strength and reducing the weight to make it more practical for travel and use on the go for sporting events and pre-competition or taking it to the gym. At 620g it’s up to 20% lighter than standard 13″ foam rollers, but being only 11″ tall it still provides 3 hand widths of dedicated zones to treat your muscles with pin point pressure and function.
