O'Neill Hyperfreak Heat Block, a performance boardshort for surf and 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 built from Hyperfreak stretch with Repreve, a blend of 53% recycled polyester, 37% polyester, and 10% elastane, finished with O'Neill's Hyperdry DWR treatment. Anti-rash hyperthread runs along the interior seams to reduce chafe during longer sessions.
Who it is for
- Surfers who want a shorter, above-the-knee cut with full stretch mobility
- Anyone moving between the boat, the beach, and the pool over the same day
- Shoppers who want a secure pocket for a key or card while in the water
A side zip pocket holds small essentials, and the flex-tie drawcord adjusts the waist without a bulky buckle getting in the way of a wetsuit or rashguard.
Wear, fit, and care
The 19 inch outseam and 8.5 inch inseam land just above the knee, built for range of motion through paddling and pop-ups rather than a loose, casual cut. Rinse in fresh water after saltwater or chlorine exposure and let it air dry to protect the Hyperdry DWR finish and the elastane stretch over repeated wear.
