KEY INFORMATION
MANERA XTEND FZ 5.4,3 MM - Men's winter fullsuit
What we like
- OCENA neoprene-free foam: Manera has innovated by replacing traditional neoprene with a foam derived from natural rubber, sourced from FSC-certified forests, along with oyster shell powder and vegetable oil.
- XTEND Fleece lining: Manera states this lining is lighter than conventional fleece. It provides excellent insulation and offers the brand's fastest drying time.
- Squareflex jersey: This ultra-stretch jersey is strategically placed on the shoulders and arms, providing maximum freedom of movement when you're holding a bar or a wing.
- SD2 Tape 2.0 seams: These seams are blind-stitched and then reinforced with a welded tape. This construction ensures the seam lasts longer and significantly reduces water entry.
- Front zip: This design allows for quick entry through the chest. The zip-free back maintains flexibility.
- Two key pockets: Each pocket includes an elastic attachment. This means you can hit the water without worrying about where to stash your car key.
- Twelve sizes: Manera offers the XTEND in short, standard, and long cuts. You'll find your perfect fit without needing to size up or down to accommodate your body type.

DETAILED DESCRIPTION
The XTEND in the Manera range
Manera organizes its wetsuits into distinct ranges: the Seafarer for entry-level riders, the XTEND for performance and mobility, and the Magma for extreme cold. The XTEND is specifically designed for riders who want a lightweight feel and freedom of movement without compromising on warmth. It's available in 3/2 mm, 4/3 mm, and 5/4/3 mm frontzip versions, plus a hooded 5/4/3 mm option. This particular model is the 5/4/3 without a hood, the thickest of the three, and is featured in the GlissEvolution winter wetsuit catalog.
OCENA, the neoprene-free foam
For 2026, Manera has upgraded the XTEND by replacing its neoprene with OCENA, a bio-sourced foam. This innovative material is made from natural rubber from FSC-certified forests, oyster shell powder, and plant-based oil. The benefits for riders extend beyond environmental impact. Manera reports an excellent warmth-to-weight ratio, which is exactly what you need from a 5.4,3 mm fullsuit that won't feel heavy on your shoulders at the end of a session.
XTEND Fleece and Squareflex jersey
Inside, you'll find the XTEND Fleece, a lighter-than-traditional fleece that Manera says retains heat and dries quickly. This is a standout feature for anyone hitting the water two days in a row. On the outside, Manera uses its ultra-stretch Squareflex jersey on the shoulders and arms, specifically for those high-movement areas. The rest of the wetsuit features a denser jersey. This protects and blocks the wind.
Seams and pattern
The panels are blind-stitched, meaning the stitching doesn't penetrate the foam, and then reinforced with a welded tape: this is the SD2 Tape 2.0. Manera strategically places these seams to avoid hindering movement or causing chafing. The pattern is initially designed in 3D on a computer before being flattened into 2D. This process results in panels that conform perfectly to the body and minimize water entry.
The front zip
Entry is through the chest, via a horizontal zip. Compared to a back zip, this design significantly reduces water ingress. The back remains entirely foam, so flexibility is maximized. Manera describes it as quick and easy to put on. While it takes a couple of tries to get the hang of it, once you do, you'll never look back. Two key pockets with elastic attachments complete the package.
Choosing your size
Manera offers an impressive twelve sizes, which is quite rare. Beyond the standard XS to XXL sizes, they also provide short (Ms, Ls, XLs) and tall (St, Mt, Lt) body sizes. The size guide, located higher on this page, cross-references the rider's height and weight, based on the Manera FW27 chart. Remember, a wetsuit should fit snugly when dry; if it's loose in the changing room, it will let water in once you're in the waves.

FAQ - MANERA XTEND FZ 5/4/3 MM
For the kiter, wing foiler, or surfer who rides in winter and wants a light, mobile wetsuit instead of heavy armor. This is the thickest version of the XTEND without a hood. For truly cold water with an integrated hood, Manera offers the XTEND Hooded or the Magma range.
The Seafarer is Manera's entry-level. The XTEND is a step up: OCENA foam without neoprene, Squareflex jersey on mobility zones, quick-drying XTEND Fleece lining. The price increases, and so does the flexibility.
