Product Info

A few years ago, finding a solid, functional, cooler water wetsuit that didn't break the bank was a tough task. But now the O'Neill 4/3 Epic Wetsuit fills that gap. With many of the same desirable features as O'Neill's high-end suits, the Epic Series offers some of the best value in the industry. Step in, zip 'er up, latch the updated velcro closure on the anti-flush neck seal and paddle into some epic waves with the O'Neill 4/3 Epic Wetsuit.

Product Details


FluidFlex™ Firewall InteriorMeasurably warmer and more flexible.

UltraFlex DS NeopreneUltraFlex is known to be super light, super flexible and super soft neoprene.

Water Temp

10-15°C (50-59°F)


Krypto Knee PadzThe knee pads are abrasion resistant and made of high-stretch neoprene. The panel has an ergonomic shaping designed to extend the life of the wetsuit and protect your knees.

Double Super Seal NeckA warm, chafe-free and comfortable two-layer design featuring Smooth Skin interior lining. O'Neill's Superseal is fully adjustable and securely locks out water.

Strategic Seamless Paddle ZonesErgonomic seamless undersleeve panels that allow for unrestricted motion and prevents rash.

Glued and Blindstitched Seam Construction (GBS)The neoprene is fully sealed with glue first, then blindstitched over the top. Blindstitching reduces seam bulk, adds durability but does not go all the way through the neoprene. In exchange, you have a durable, warm product that prevents flushing.
