Volare Swim Skins Size Chart Volare Swim Skins feature cutting edge technology and are entirely constructed from hydrophobic material to enhance hydrodynamics. Constructed from premium Italian fabric, this ground breaking Swim Skin features a Teflon coated surface which reduces drag. To further reduce drag all seams are thermo bonded with taped seams for additional strength. Removing stitching and ridge lines from the design creates a more hydrodynamic profile. A YKK Locking Zipper allows for a super fast transition. In the Zip down position it is locked and secure. To take off simply flick the zip latch up and pull on a shoulder. The Zip will then slide to the base, allowing for quick removal of the suit. No cords are required to operate this system. The Volare Swim Skin is designed to be worn as a compression fit garment. Expect it to be a tighter fit than your wetsuit. Take your time and inch the garment up until you have it over your waist, you will need help zipping up the garment. Like a wetsuit it will feel looser in the water so a tight fit is a must. Remember it's not a race to put it on, just to take if off.
