Scuba Wetsuit: Choosing, Fitting and Caring for Your Gear

If you’re planning a dive around the UK coast, the right wetsuit can make the difference between an enjoyable dive and a miserable one. A good wetsuit keeps you warm, protects you from scratches, and lets you move freely underwater. Below you’ll find straight‑to‑the‑point advice on how to choose the right suit, get a perfect fit, and look after it so it lasts season after season.

How to Choose the Right Wetsuit

First, think about the water temperature you’ll face most often. In the colder waters of Scotland or the North Sea, a 7 mm or 7/5 mm suit is common. For milder spots like Cornwall or the Isle of Wight, a 5 mm or 5/3 mm suit usually does the job. The first number is the thickness of the torso panel, the second is the thickness of the limbs – thinner limbs give you more flexibility.

Next, consider the material. Most wetsuits use closed‑cell neoprene, which traps a thin layer of water that your body heats up. Look for suits with super‑stretch neoprene if you need extra mobility for underwater photography or tight passages.

Seams matter too. Sealed seams (glued and blind‑stitched) keep water from entering the suit, while taped seams add extra protection. If you’re on a budget, a glued‑stitched suit will still keep you warm, but a fully sealed suit gives the best performance.

Finally, think about the suit style. Full‑body suits are the go‑to for cold dives, but a shorty (short arms and legs) can be fine for summer trips. Some divers prefer a two‑piece system – a jacket and separate pants – because it’s easier to put on and take off, especially in cold conditions.

Caring for Your Wetsuit

Rinse your suit with fresh water after every dive. Salt, sand, and chlorine can break down neoprene over time. Use a mild, silicone‑based cleaner if you need to remove stubborn grime, but avoid harsh detergents.

Never wring or twist the suit. Instead, gently squeeze out excess water and hang it inside‑out on a wide hanger. Let it dry in a shady, well‑ventilated spot. Direct sunlight can degrade the neoprene and cause fading.

Storage is simple: roll the suit loosely, avoid folding creases, and keep it away from sharp objects. If you store it for a long period, a light coat of wetsuit spray can help preserve flexibility.

When you notice a small tear or a seam starting to split, repair it right away with wetsuit cement or a patch kit. Fixing problems early stops them from spreading and saves you money on a full replacement.

With the right fit and proper maintenance, your scuba wetsuit will keep you comfortable on countless dives along the UK’s stunning coastline. Remember, the best suit is the one that matches your water temperature, moves with you, and stays in good shape year after year.
