Sheet updated September 2026
The Manera Seafarer U-Zip 5.4,3 mm is the thickest fullsuit in the Seafarer U-Zip range, and it's the first to feature Manera's innovative new entry system. This fullsuit features three thicknesses: 5 mm, 4 mm, and 3 mm. Manera offers the Seafarer U-Zip in five models: two with an integrated hood and three without. This particular model is the thickest of the three non-hooded versions. The U-Zip is a smaller zip than a classic one. It pivots flat. This allows it to follow your body's natural lines, rather than creating a rigid straight line across your torso.

DETAILED DESCRIPTION
Its place in the Seafarer U-Zip range
Manera offers the new entry system across five models: two hooded versions (5.4,3 mm and 4.3 mm) and three non-hooded versions (5.4,3 mm, 4.3 mm, and 3.2 mm). This is the thickest of the three non-hooded options. The hood, boots, and gloves are not included; you choose them separately. We also offer the Seafarer U-Zip 4.3 mm.
The U-Zip system
The U-Zip is smaller than a classic zip and can pivot flat. This rotational freedom allows for closing paths that follow the body's natural lines. It is positioned on the shoulder, chest, and shoulder blade. Manera states this limits hard points during paddling and repetitive movements. This improves comfort and freedom of movement.
The back and the pull tab
A stretch neoprene zone runs along the zip at the shoulder blades. This increases back flexibility. The pull tab is very easily accessible for smooth opening and closing. The U-Zip is the perfect balance between ease of donning and continuous watertightness from shoulder to shoulder, where water entry matters most.
The Seafarer construction
The Seafarer is Manera's most direct range. It focuses on warmth, comfort, and durability. It features SFOAM limestone-based foam. This offers the best flexibility, warmth, and durability ratio on the market. The XTEND Fleece lining's loops insulate and dry quickly. It also includes soft and light XTEND Jersey, SD2 Tape seams on 100% of the fullsuit, a 3D-designed pattern, and a water strainer to drain water.

FAQ - MANERA SEAFARER U-ZIP 5.4,3 MM
Manera has released five models featuring the U-Zip system: two with hoods (5.4,3 mm and 4.3 mm) and three without hoods (5.4,3 mm, 4.3 mm, and 3.2 mm). This particular fullsuit is the thickest of the three non-hooded options. In the GlissEvolution catalog, we classify it as a winter fullsuit.
Our size guide cross-references your height and weight, based on the Manera FW27 chart. Twelve sizes are available, with 't' for taller body builds and 's' for shorter ones. This ensures a perfect fit without needing to size up or down. If you have any doubts, visit the store; all sizes are in stock.
The zip is smaller and pivots flat. This allows it to follow a curved path along the shoulder, chest, and shoulder blade, rather than a straight line across the torso. Manera adds a stretch neoprene zone along the zip at the shoulder blades. The stated goal is twofold: ease of donning and a continuous closure from shoulder to shoulder.
No. Manera offers two versions with integrated hoods in the U-Zip range (5.4,3 mm and 4.3 mm), but these are separate models. For this fullsuit, the hood, boots, and gloves are separate purchases.
Our shop is in Pornichet, Loire-Atlantique, and wetsuits are in stock. Trying them on is the only sure way to decide between two sizes. Our team rides in the bay all year and answers by phone and email.
