Fourth Element's RF Vest is designed to be worn on top of the RF1 Full Suit, giving an extra layer of warmth on your torse by increasing coverage to 6mm for warmth and including a hood to help reduce heat loss. 

The RF range is made with Glideskin, Smoothskin and lined neoprene for smooth, easy movement through the water, without adding any additional bulk to the shoulders. The Glideskin panels have a hydrophilic coating, reducing friction as you move through the water, meaning your can glide through the water and focus on your surroundings. 

The hood on this vest has ear holes to assist with equalising, making it quicker and more effective by allowing a small amount of air into the ears to help prevent squeeze as you descend.
