When the weather turns colder, you can stay in the water with a 4/3mm wetsuit. The 4/3 full wetsuit (pronounced “four-three”) provides warmth and protection in water temperatures of 52 degrees and higher. This is the wetsuit that athletes reach for when waters are chilly, especially for watersports like surfing, SUP, wakeboarding, or general water activities. With two thicknesses of neoprene (4mm torso and 3mm arms and legs) the mens 4/3 wetsuit gives you both warmth and mobility for surface water sports.

4/3 Full Wetsuit

When the seasons change, a 4/3 full wetsuit can help keep you warm and safe in the water. When you choose a thicker wetsuit like a mens 4/3 wetsuit, extra stretch is important for both warmth and mobility.  All our 4/3 wetsuits are made from flexible, durable material that lets you move with comfort. You can choose a 4/3mm wetsuit with the features and construction to meet your needs. A suit with sealed seams (also called GBS, or, glued and blindstitched, seams) has interior sealing and lets very little water through. Another option is a mens 4/3 wetsuit with sealed and taped seams, with taping on the interior and exterior seam to provide reinforcement. You may also consider investing in a semi-dry wetsuit. This option keeps the wearer semi-dry thanks to sealed and taped seams, poly-fleece panels, and anti-flush gaskets to reduce water entry.
