Choosing the right 4-3mm wetsuit can make all the difference
in how you feel in the water. For many riders and watersport enthusiasts, a 4-3mm suit hits the sweet spot between warmth and flexibility — exactly what you need when the season starts to cool but you’re not ready to jump straight into a winter-weight suit. At Ocean Sports Board Riders, we’ve brought together
a wide collection of 4-3mm wetsuits from leading brands so you can find the gear that suits your body, your sport and how you like to spend your time in the sea or on the board.
A wetsuit with 4mm neoprene through the torso and legs and
3mm through the arms gives you insulation where it matters most — around your core — while still allowing your shoulders and arms to move freely when you paddle, stroke or push off a wave. It’s designed to keep you comfortable from spring into autumn, and even through milder winter days depending on conditions.
Cold water can shake confidence and cut sessions short, but
when your suit works with your body — stretching as you reach, paddling as you push for a wave, and insulating your core as the air temperature drops — it becomes a reliable layer that supports your time on the water. That’s true whether you’re surfing beach breaks, gliding on a SUP, practicing turns in a kayak or simply enjoying being in the sea with friends.
Our team are here to help you think about fit, thickness and
how you plan to use your suit. Because the right 4-3mm wetsuit shouldn’t just feel warmer — it should help you make the most of every session, extend your season and give you the confidence to step into cooler waters and enjoy them.
C-Skins wetsuits are a name you’ll hear again and
again in British watersports circles — especially among surfers,
bodyboarders, paddleboarders and open-water swimmers who want gear made by people who truly understand cold-water conditions. Born from a passion for the sea and tested in some of the harshest waters of northern Europe, C-Skins has been refining wetsuit design and construction for decades so that when you’re in the water, your kit feels like a reliable partner, not just another piece of clothing.
O’Neill wetsuits are among the most iconic and trusted
wetsuits in the world of watersports, built on a legacy that goes right back to where modern surfing and wetsuit design began. The brand’s story starts with Jack O’Neill, who is credited with inventing the neoprene surf wetsuit in the 1950s so surfers could stay out longer and enjoy the water even when temperatures dropped. That pioneering spirit — a desire to extend sessions and make cold water more welcoming — still shapes every suit the company produces today.
Rip Curl wetsuits are among the most recognised and respected wetsuit ranges in watersports, known for their blend of heritage, innovation and performance. Born in 1969 in Torquay, Australia, Rip Curl began as a surf company that quickly became deeply involved in wetsuit design — pioneering many of the technologies riders now take for granted. This long history of
development means Rip Curl gear often feels familiar and trustworthy to surfers, bodyboarders and open-water adventurers alike.
