"E'Tanche" used in the 9402 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 vapour, which means perspiration in the form of water vapour 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.

Specification Info:

Water flowing is rectified and friction drag can be reduced. Super chlorine resisting Urethane elastic fiber. Professional race use material. The drag reducing process on the part causing the biggest drag force as well as the enhancement of elasticity of the fabric contributes to the final improvement in the competition for the swimmers. 82% Polyamide, 18% Lycra
