The O'Neill Epic 5/4 is our go-to winter wetsuit for performance and value. This chest-zip version offers extra comfort from its' watertight entry system. 
 
Now fully double-lined, it offers extra strength and longevity without compromising flexibility. Featuring many of the same premium details as O’Neill’s top tier wetsuits, the Epic Chest Zip includes a double-seal neck closure to keep water out and the LSD (Lumbar Seamless Design) for maximum mobility and comfort. 

Whether you're paddling out, carving waves, or braving cooler waters, this wetsuit delivers warmth, flexibility, and long lasting performance, making it a go to choice for surfers who demand quality without the premium price tag.
 
Here's what O'neill have to say: 
The Epic has many of the same features as our high-end wetsuits, including 100% UltraFlex neoprene, double seal neck close, LSD (lumbar seamless design) and re-engineered cover blackout zip. Clean graphics and sharp style lines makes the epic the best value in the industry.
