O'Neill Hyperfreak Heat Block, built to move from the lineup to the pool
The O'Neill Hyperfreak Heat Block Boardshort is a go-to performance boardshort for any situation, whether you are surfing or hanging by the pool. Hyperfreak stretch fabrication offers flexibility and comfort while O'Neill Hyperdry speeds up drying time.
Materials and construction
This men's boardshort has a 19 inch outseam and 8.5 inch inseam, a fit that sits just above the knee. It is constructed from Hyperfreak stretch with Repreve, a blend of 53% recycled polyester, 37% polyester, and 10% elastane, finished with O'Neill's Hyperdry DWR. Anti-rash hyperthread lines the interior seams to reduce chafing over a full session.
Who it is for
- Surfers who want an above-the-knee fit with real stretch mobility
- Anyone splitting a day between the boat, the beach, and the pool
- Shoppers who want a secure zip pocket for small items in the water
The side zip pocket secures a key or card, and the flex-tie drawcord lets you adjust the waist without a rigid buckle.
Wear, fit, and care
At 19 inches outseam and 8.5 inches inseam, this fit sits just above the knee, designed for range of motion through paddling and turns rather than a baggy, casual cut. Rinse thoroughly in fresh water after ocean or pool use and air dry to protect the Hyperdry DWR coating and the elastane stretch over time.
