Classic O'Neill Style, Built for the Water
The O'Neill OG Sideline Cruzer 18 Boardshort is a heritage-inspired men's boardshort that pairs retro California surf style with modern performance fabric. The 18-inch outseam sits well above the knee, giving you unrestricted range of motion whether you are paddling out, riding a wave, or hanging on the beach. Part of the O'Originals line, this short channels the look O'Neill has refined since 1952.
Performance Fabric and Construction
The Cruzer 18 is built from a stretch-engineered blend of 74% recycled polyester, 18% cotton, and 8% elastane. The recycled polyester content reduces virgin material use without sacrificing the quick-dry performance you need after a session. The elastane gives the fabric four-way stretch so the short moves with you in and out of the water.
O'Neill Hyperdry DWR
Hyperdry is O'Neill's durable water-repellent (DWR) finish applied to the outer fabric. It causes water to bead and roll off the surface rather than saturating the weave, which means the short dries faster and stays lighter during wear. The finish holds up through repeated wash cycles better than untreated fabrics.
Anti-Rash Hyperthread Lining
The interior is lined with O'Neill's Hyperthread, a fine-woven anti-rash fabric designed to reduce friction against the skin during extended sessions. Whether you are prone to inner-thigh chafe on long paddle-outs or just wearing the short all day, the Hyperthread lining keeps things comfortable without adding bulk.
Fit and Pocket Layout
The 18-inch outseam places the hem well above the knee for a fit that reads retro without being restrictive. The tunnel drawcord at the waist lets you dial in the fit over a wetsuit or board without fumbling with an exterior tie. Storage is covered by two side hand pockets and a single back pocket, giving you enough room for keys and wax without loading down the short.
Sustainability
The OG Sideline Cruzer 18 is made with recycled materials. The recycled polyester in the fabric blend diverts post-consumer plastic from landfill and ocean-bound sources, reducing the carbon and water footprint compared to virgin polyester production.
