The Yonex AC-1108EX Red Black sports towel is cool, soft and comfortable. The new Yonex towel is now made using cotton and rayon to help absorb moisture better. Rayon absorbs more moisture and lighter than cotton, but it is not as strong as cotton, especially when it is wet. The combination of these two materials balance the absorbency and strength of the towel. The AC-1108EX is excellent for absorbing sweat during game. It is also lightweight, compact, and convenient to carry.
