For summer, a 3mm or 2mm shorty, and a 3mm fullsuit with waterproof seams for morning patrols and general late spring and early autumn surfing. A 4mm suit is best for early spring and late autumn, before winter sets in. In most regions, a 5mm wetsuit is enough for winter, especially when teamed with boots, gloves, and a hood. Some people can switch back and forth between 3mm and 4mm suits without problems, but most surfers prefer one size for all. You don't need a wetsuit that is too small. It's better to have a big suit than a small one. Even if you can get away with a smaller size, it's still very important to try on any new wetsuit before buying it so that you know how it fits over your arms and legs. There are many different styles of wetsuits, so make sure that you try on several sizes before making a choice. The average person has a height of 69 inches (175 cm) and weighs 166 pounds (75 kg). Standard wetsuit sizes range from X-small (4-6), small (8-10), medium (12-14), large (16-18), to x-large (20). Most manufacturers also sell one-size-fits-most wetsuits. These usually fit someone who is either much smaller or much larger than the standard sizes; they are labeled as "Small/Medium" or "Large/X-Large".
