YINGFA 9402 LIGHTNING ARROW SHARK-SKIN MEN’S JAMMERS – FINA APPROVED
FINA APPROVED. Yingfa has found that the fabric “E’Tanche” used in the 9402 Apollo is waterproof. The pores in the fabric are about 20,000 times smaller than a drop of water, however the pores are actually 700 times bigger than a droplet of water vapor, which means perspiration in the form of water vapor can pass out through the membrane. Therefore the fabric is breathable while allowing the swimmer to remain dry and therefore maintain a better position in the water.
