What Our Gearhead(R) Experts Are Saying: "I wore the Seafarer 5/4/3 on a windy NorCal session and stayed warm the whole time. The fleece lining dried fast between surfs, and I had great mobility in the arms-super solid winter suit for the price." When winter swells are firing and water temps drop, we zip into the Manera Seafarer FZ 5/4/3mm Wetsuit for full-session warmth and confidence. Built with a strategic blend of thickness-5mm in the core, 4mm in the arms and shoulders, and 3mm where mobility matters most-this wetsuit delivers balanced insulation and flexibility where we need it most. Inside, the X10D fleece Plus lining traps heat while drying quickly between sessions. SD2 TAPE 2. 0 reinforces critical seams, adding durability and keeping cold water out. With a front-zip entry that locks in warmth and a tailored, movement-friendly fit, the Seafarer is a go-to for cold-water surfing without all the fluff.
