O'NEILL UPF SLUB RELAXED SS WVN SHIRT
Pickup currently unavailable at BSS
Built for the Beach, Worn All Day
The O'Neill UPF Slub Relaxed SS Woven Shirt is a short-sleeve button-up designed for warm-weather living. The slub-textured woven fabric gives it a lived-in, casual look straight off the rack, while a thoughtful blend of performance features keeps it functional from the water's edge to the boardwalk.
O'Neill has been shaping California surf culture since 1952, and this shirt reflects that heritage: relaxed enough to wear all afternoon, refined enough to walk into anywhere.
UPF 50+ Sun Protection
The fabric carries a UPF 50+ rating, blocking the vast majority of UV radiation. That protection is woven directly into the construction, not a topical treatment, so it holds up over repeated wear and washing. For anyone spending long hours outdoors in South Florida sun, it is a meaningful upgrade over a standard woven shirt.
O'Neill Hyperdry Moisture Wicking
O'Neill's Hyperdry technology moves sweat away from the skin and accelerates evaporation. The lightweight 125 GSM fabric weight supports this process, keeping the shirt breathable and comfortable even in humid conditions. It dries quickly after a splash or a long afternoon outside.
Fabric and Construction
The blend of 68% polyester, 24% cotton, and 8% elastane gives the shirt its core character. The polyester and elastane contribute durability, shape retention, and a slight mechanical stretch that lets the relaxed fit move with the body rather than restricting it. The cotton content softens the hand and adds the natural texture that reads through the slub weave. At 125 GSM, the fabric is genuinely lightweight without feeling sheer.
Additional construction details include a chest pocket with an O'Neill tab, wrinkle-resistant finishing that keeps the shirt looking clean with minimal effort, and an all-over print that covers the full body of the shirt for a bold, intentional look.
Fit and Wear
The relaxed fit is cut with extra room through the chest, shoulders, and hem. It is not oversized, but it is designed to move freely without pulling or binding. The curved shirttail hem works untucked, which is the intended wear for this style. The point collar and standard button-front closure give it enough structure to cross from casual to smart-casual territory without effort.

Frequently Asked Questions
- What does UPF 50+ mean on a woven shirt?
- UPF 50+ means the fabric blocks the large majority of the sun's ultraviolet radiation from reaching the skin. Unlike sunscreen, this protection is built into the fiber construction and does not wash off or degrade with normal use.
- What is O'Neill Hyperdry moisture wicking?
- Hyperdry is O'Neill's moisture-management technology. It pulls sweat away from the skin toward the outer surface of the fabric where it can evaporate faster, keeping you cooler and drier during warm-weather activity.
- Is a slub woven shirt the same as a linen shirt?
- No. A slub woven shirt uses a yarn with intentional thickness variations that create a textured, natural-looking surface. This shirt is made from a polyester, cotton, and elastane blend, giving it the casual texture of a slub weave alongside performance benefits like moisture wicking and wrinkle resistance that linen does not offer.
- Is this shirt wrinkle resistant?
- Yes. The fabric has wrinkle-resistant finishing built in, which means it holds its shape out of the wash and handles packing well without needing to be ironed for everyday wear.
- Can I wear this shirt in the water?
- This is a woven button-up shirt, not a rash guard or swim top. It is designed for beach and outdoor wear rather than swimming. The Hyperdry fabric dries quickly if it gets wet, but it is not built for submersion.
- How does the relaxed fit compare to a standard shirt fit?
- The relaxed fit has additional room through the chest, shoulders, and body compared to a slim or regular fit. It is intended to be worn untucked and to move freely without pulling, making it well suited for outdoor and casual wear in warm climates.
- Where can I buy the O'Neill UPF Slub Relaxed Woven Shirt?
- It is available in store and online at Island Water Sports, serving South Florida's surf and outdoor community since 1978.
