Paddle Out With the Hyperfreak Mysto 20 Boardshort
Searching for the Hyperfreak Mysto 20, you are looking at one of O'Neill's core performance boardshorts, built to extend a session and hold up in demanding water conditions. The two features doing the work here are Hyperfreak stretch for mobility and O'Neill Hyperdry, which speeds up drying time so the short feels comfortable once you are back on the sand.
What's Built Into This Boardshort
This is a men's boardshort with a 20 inch outseam and an at the knee fit, longer and more traditional than O'Neill's shorter cuts. It has anti-rash hyperthread construction to reduce chafing, a back patch pocket, a flex tie drawcord at the waist, and a scallop hem detail. The fabric is 90% polyester and 10% elastane.
Who Should Wear the Mysto 20
The at the knee length and traditional fit make this a good pick for anyone who wants a boardshort that reads more classic than the shorter, above the knee performance cuts, whether you are surfing, out on the boat, or just spending the day around the water. The back patch pocket is a practical touch if you want somewhere to stash a wallet or key when you are not actually in the water.
Fit, Wear, and Care
The flex tie drawcord lets you adjust the waist fit, and the anti-rash hyperthread lining is there specifically to reduce irritation during long paddling sessions. Rinse the boardshort in fresh water after saltwater or chlorine exposure to protect the fabric and hardware, and let it air dry to preserve the Hyperdry finish rather than relying on a hot dryer cycle.
About O'Neill
O'Neill is the original California surf lifestyle brand, in business since 1952. The Hyperfreak name covers O'Neill's current performance boardshort platform, and the Mysto 20 sits in that lineup as a more classic length option.
