The textile fabric in the Yingfa 937 Fina Approved suits is water resistant because the fabric when knitted or woven tight provides a limited barrier between the body and the water.It reduces drag in the water and allows the swimmer to sit higher in the water and therfore providing less drag and restriction.
It is high in performance which maximises speed in the water and improves glide times by reducing drag and increasing water flow.
Competition swimwear ,no padding and no lining.
Mesh seam on the back improves water flowing and reduces drag.
Fina approved maybe you will receive them with a Fina approved sign on bottom area or not.It can't be chosen.
It is meant for racing and therefore you should expect a very tight fitting swimsuit and no more baggy legs as often found in the major brands.
Why pay $495.00 for a Speedo Ladies LZR Kneeskin swimwear when you can purchase a Yingfa Escolar 937 for $39.99.
