The Apoc series: Ride Engine developed the Apoc series with close collaboration from athletes who know exactly what they want, and need, from their equipment. Ranging from our warmest suit, the fully-sealed, fleece-lined, Apoc 5/4, to our sealed 4/3 long suit and 3/2 long suits and 2m shortys, the Apoc is a full-range front-zip lineup designed with the utmost attention to detail to keep users warm and comfortable as they pursue their water-bound passions. All suits in the Apoc series are front-zip and feature internal neck gaskets to reduce flushing; the 5/4 and 4/3 suits have internal poly-fleece lining for added warmth and water retention and all are made from limestone-based neoprene.
