If you surf, paddle board, swim, kite, or do anything that involves large, cold bodies of water, you will feel the benefits of a wetsuit. Sure, those hardy cold-water folk out there might disagree, but try surfing in the English Channel in January. We give it 10 minutes before the towel is well and truly thrown in.
The fact of the matter is that modern wetsuits are excellent at extending sessions in cold water without restricting freedom of movement. With the right gear (neoprene hats, boots and gloves), you can surf in the Arctic Circle and still come away with your digits intact.
