Men's wetsuit for regular sessions
O'Neill Epic 4/3 Chest Zip Full is a men's neoprene wetsuit designed for regular use in cooler conditions. It incorporates several features found in O'Neill's higher-end wetsuit ranges while keeping the construction practical and durable.
The latest version is fully double lined, increasing durability and performance during regular use.
UltraFlex and freedom of movement
The suit is built with UltraFlex, a flexible material designed to support unrestricted body movement.
Strategic Seamless Paddle Zones reduce seam placement in areas where the arms move most. This helps limit restriction in zones where mobility is especially important during paddling and other dynamic upper-body movements.
F.U.Z.E. Closure
The F.U.Z.E. Closure (Front Upper Zip Entry) uses a front-entry zipper positioned across the upper section of the wetsuit.
This design avoids a long back zipper and helps maintain a more flexible upper-body construction.
Double Super Seal Neck
The Double Super Seal Neck creates additional sealing around the neck to help reduce water entry.
Combined with the Glued and Blindstitched Seams, it supports reduced water exchange during the session.
Glued and Blindstitched Seams
The panels are joined using Glued and Blindstitched Seams. The seams are glued and stitched without the needle passing completely through the material.
This construction helps reduce water penetration through the panel connections.
Reinforcement and practical details
The knees are protected with Krypto Knee Padz, reinforcing an area exposed to frequent wear.
Hand-Cuff Stitch Sleeve Anchor reinforces the sleeve ends, while the External Key Pocket with Loop provides a secure place for a key.
