Fourth Element's RF Vest is designed to be worn as an additional layer with the RF1 Full Suit, increasing coverage on your torso to 6mm for warmth and including a hood. 

The RF range is made with Glideskin, Smoothskin and lined neoprene for streamlined easy movement through the water, without bulk around the shoulders. The Glideskin panels have a hydrophilic coating, reducing friction as you move through the water. 

The hood on this vest has ear holes to assist with equalising quickly and effectively, allowing a small amount of air into the ears to help prevent squeeze as you descend.
