DETAILED DESCRIPTION
Key Ride Feel
You'll experience a warm wetsuit without the bulk. TechnoButter 3 provides incredible flexibility, while TB3X enhances warmth in critical areas. The 5/4+ cut adds an extra 0.5 mm of material compared to the HyperFreak Comp, giving you increased thermal protection. On the wave, you'll maintain full shoulder mobility for paddling and loading your stance.
Sizes and Fit
The cut follows the HyperFreak lineage, with a construction focused on a snug yet non-restrictive fit. Available sizes cover S, M, MS, MT, ST, LS, LT, XL; choose according to your usual O'Neill measurements. If you're between two sizes, opt for the larger size for greater thermal comfort.
Materials and construction
This wetsuit utilizes TechnoButter 3 and TB3X neoprene to reduce weight while maintaining elasticity and warmth. The minimal seams design limits water entry points, and the 360° barrier with drain vents helps to expel accumulated water. The F.U.Z.E. closure makes entry easy without adding a large back opening.
On-water behaviour
The wetsuit remains compact when wet, with less water trapped thanks to the vents and 360° barrier. When paddling or seeking an explosive stroke, you'll maintain a full range of motion in your arms thanks to TechnoButter 3. The 5/4+ thickness is designed for cool to cold sessions where warmth is a priority.
Who is it for?
The O'NEILL HYPERFREAK 5/4+ CHEST ZIP is for riders who want a great balance between warmth and flexibility for cold water sessions. It's ideal for regular Surf, paddle, or windsurf enthusiasts looking for a high-performance wetsuit for winter.
Buying advice
Check your usual O'Neill fit and consider layering if you're riding in very low temperatures. If shoulder ease is a priority, confirming the size in-store is helpful. Bring wetsuit accessories like gloves and a hood if conditions drop below freezing.
