Built for the Water, Engineered by Florence Marine X
The Florence Marine X 1.5mm FlatLock Wetsuit Jacket is a precision-built wetsuit top that raises the standard on what a jacket in this category can do. Trusted by John John Florence as a daily essential on the North Shore, this jacket pairs premium materials with performance patterning to deliver genuine comfort across long tropical sessions.
Yamamoto Foam Rubber Construction
The jacket is constructed entirely from Yamamoto foam rubber, one of the most respected neoprene materials in surfing. Yamamoto rubber is sourced from limestone-based materials rather than petroleum, which translates to superior stretch, lightweight feel, and exceptional durability over time. The result is a wetsuit top that moves with your body rather than fighting against it, session after session.
FlatLock Stitching for Chafe-Free Wear
Flatlock stitching lies flat against the skin on both the inside and outside of the seam. Unlike overlock or blind-stitch constructions that can create raised ridges, flatlock seams stay flush with your body, eliminating the friction points that cause chafing during extended paddling and surfing. This is especially important through the underarms and torso where movement is constant.
Performance Fit and Retention Features
Performance patterning gives the jacket a secure, body-mapped fit that stays in position when you paddle hard, duck dive, or wipe out in heavy water. The lower-collared design avoids the flush points common on higher-collared jackets, keeping water out without restricting head movement or creating pressure on the neck. A boardshort tie at the hem locks the jacket down so it stays tucked in no matter what the water throws at you.
The Florence Marine X burgee heat transfer on the left arm is a clean, low-profile branding detail that sits flat and does not interfere with arm movement.
When and Where to Wear It
At 1.5mm, this jacket is purpose-built for warm to tropical water temperatures where you want core coverage without the bulk of a full suit. It is ideal as a standalone piece in warm conditions or as a layering jacket under a full suit when the water cools. Flatlock construction at this thickness means it is optimized for warmth-to-weight performance in the conditions where most South Florida and tropical surfers spend their time.
Care and Maintenance
Rinse the jacket thoroughly in fresh water after each session to remove salt, sand, and chlorine. Dry flat or hang by the body, not the collar, to preserve the material's shape. Avoid prolonged direct sunlight when drying, as UV exposure degrades neoprene over time. Store flat or loosely rolled away from heat sources.

Frequently Asked Questions
- What makes Yamamoto foam rubber different from standard neoprene?
- Yamamoto foam rubber is manufactured from limestone-based calcium carbonate rather than petroleum-derived materials. This gives it superior elasticity, a lighter weight, and longer-lasting durability compared to conventional neoprene. It also tends to retain warmth more efficiently at the same thickness.
- What is flatlock stitching and why does it matter on a wetsuit jacket?
- Flatlock stitching interlocks threads from both sides of the seam so the join lies completely flat against the skin. Unlike raised seams, flatlock seams do not create friction ridges, which prevents chafing during long surf sessions. It is the preferred construction for warm-water wetsuits where maximum skin contact and comfort are priorities.
- Is the Florence Marine X 1.5mm FlatLock Wetsuit Jacket good for warm water?
- Yes. At 1.5mm, this jacket is designed for warm to tropical water conditions. It provides core coverage and UV protection without the thermal buildup of thicker neoprene. The Yamamoto construction keeps it lightweight and highly stretchy so it does not restrict movement even in warmer water.
- Does the jacket flush or ride up in the water?
- The lower-collared design reduces flush at the neck compared to higher-collared wetsuit tops. The boardshort tie at the hem anchors the jacket in place so it stays down during heavy wipeouts and paddling.
- Can this wetsuit jacket be worn as a layer under a full wetsuit?
- Yes. The 1.5mm thickness and form-fitting performance patterning make it a practical layering piece under a thicker full suit when temperatures drop or you want extra core warmth.
- Is the Florence Marine X 1.5mm FlatLock Wetsuit Jacket available at Island Water Sports?
- Yes. It is available in store and online at Island Water Sports. Check the variant picker above for current options.
- How should I care for the Florence Marine X wetsuit jacket to make it last?
- Rinse thoroughly in fresh water after every session to remove salt, sand, and chlorine. Hang or lay flat to dry out of direct sunlight. Store flat or loosely rolled away from heat sources. Avoid folding on the same crease repeatedly to protect the Yamamoto foam rubber.
