Body Seams
Specifically placed body seams designed so that you get extra compression where it is most needed. This key compression around muscles reduces energy lost through mucle vibration while also helping with circulation to bring more oxygen to muscles when they need ti the most.
Teflon Coating
The Teflon Coating, that is usually paired with the Sharkskin material, channels water and helps to reduce resistance, allowing better gliding distance in the water.
