World Aquatics-approved water-repellent racing jammer designed to enhance glide, muscle compression, and performance. Strategically placed seams provide targeted compression. Blue with gold contrast accents. 71% polyester, 29% spandex (elastane) Note! Yingfa uses the Chinese sizing standard (CN), with sizes indicated as XS, S, M, etc. These sizes do not correspond directly to European sizing. To make size selection easier, we have converted Yingfa's CN sizes to their equivalent inch sizes, which is the most commonly used sizing system for swimwear.
