Wetsuit Temperature Guide

Ultimate Yamamoto Wetsuit Thickness Guide

Whether you’re chasing dawn barrels in the shoulder season or charging winter breaks, picking the right wetsuit thickness can make your session warmer, more comfortable, and more fun. This guide helps you understand what thickness works best for different conditions — from tropical reef breaks to cold-water ventures.

Below is a handy guide to help you decide what thickness works best for your conditions. Remember, your own body heat, wind, air temperature, and session length can all influence how warm you feel in the water.

How Wetsuit Thickness Works

Wetsuits work by trapping a thin layer of water between your skin and the suit. Your body warms that layer, and the neoprene holds the heat close to your core to keep you comfortable in cooler water. The thicker the neoprene, the better it insulates — but too much thickness in the wrong conditions can restrict movement and tire you out.

What sets our suits apart is our use of premium eco-friendly Yamamoto rubber — a high-performance limestone neoprene that’s lighter, warmer, and more flexible than standard neoprene, with a greener footprint. That means you get more warmth with less bulk, better stretch for paddling, and a material choice that aligns with your values.

Choosing a wetsuit is as much about feeling confident as it is about temperature charts. With eco-forward Yamamoto neoprene powering your suit, you get warmth, flexibility, and performance — all while minimizing your environmental impact. Whether you’re ripping summer swells or exploring big winter breaks

Tip:

If you’re on the edge of two thicknesses, think about how long you’ll be out and how cold you get. A slightly thicker suit with our Yamamoto rubber can often keep you warmer with equal flexibility. Remember our suits run slightly warmer than standard neoprene!
