DETAILED DESCRIPTION
Its place in the Seafarer U-Zip range
Manera offers its new entry system across five models: two hooded versions (5/4/3 mm and 4/3 mm) and three hoodless versions (5/4/3 mm, 4/3 mm, and 3/2 mm). This particular model is the middle thickness among the three hoodless options. You'll find it in the GlissEvolution catalog under wetsuits for cooler water. The Seafarer U-Zip 5/4/3 mm is also available in our catalog.
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 and chest, and also on the shoulder blade. Manera states this limits hard points during paddling and repetitive movements, improving comfort and freedom of movement.
The back and the pull tab
A stretch neoprene zone runs along the zip at the shoulder blades, increasing back flexibility. The pull tab is very easily accessible for smooth opening and closing. Manera presents the U-Zip as 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, focusing on warmth, comfort, and durability. It features SFOAM limestone-based foam, which Manera claims offers the best flexibility and warmth, as well as durability, 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 4.3 MM
The entry system and construction are identical, as is the size grid. Only the thickness changes: 4 and 3 mm here, 5, 4, and 3 mm on the other model. In the GlissEvolution catalog, the 4/3 mm is listed as mid-season and the 5/4/3 mm as winter.
The size guide above cross-references the rider's height and weight, according to the Manera FW27 grid. Twelve sizes are available, with longer body sizes in 't' and shorter ones in 's'. All twelve are in stock at the store; trying it on is the most reliable method.
The zip is smaller and pivots flat. This allows it to follow a curved path along the shoulder and chest, rather than a straight line across the torso. It also follows a curved path along the shoulder blade. 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.
Yes, Manera offers a Seafarer U-Zip 4/3 mm with an integrated hood, which is a distinct model. On this one, the hood, boots, and gloves are not included.
