The O'Neill Womens Epic 5/4 back zip wetsuit is our most popular entry level wetsuit all year round and for very good reason. We love the stretchy neoprene, seam free paddle zones (meaning there are no seams under the arms), double seal neck closure, glued and blind stitched seams and the covert blackout back zip (all three meaning less water will get in). 
In 5/4mm thickness this wetsuit is suitable for Irish conditions all year for any watersport like surfing, paddle boarding, windsurfing, kitesurfing or kayaking. We also love the price - this is a great value wetsuit we would highly recommend.

  • Glued in covert zipper construction with Back-out zipper
  • seam free paddle zones
