We are again taking advantage of the advances in fabric science by introducing Spiro spun fabric to our athletes. This new fabric has enhanced flex and breathability. Athletic movement is unrestricted in any training environment and if fashion is important to you, you can appear athletic even if you are not. Softer and lighter than even last year’s material, it whisks moisture to the surface for quicker drying.
