Wearing Thermals Under a Wetsuit

8 August 2023

Wetsuits are a must for water-based activities, but what do you wear under a wetsuit? For some, swimwear may seem like the obvious choice, but swimwear doesn’t protect you from the colder waters like thermals do. But can you wear thermals under a wetsuit? Yes! Although wearing thermals under your wetsuit may initially sound off-putting, wetsuit thermals offer a range of benefits to the wearer.

Thermals are not just for the winter months. They offer great versatility to water sports fans since they can be worn alone – in the form of a top, shorts, or leggings – or worn underneath your wetsuit to enhance your experience in or around the water. They are also available in a range of materials and styles, including short-sleeve and long-sleeve variations.

Advantages of wetsuit thermal layering

Increased insulation

Wearing thermals is perfect for winter sessions out on the water. Even in a warmer climate, the water can remain cold. Using quality thermals can provide significant insulation to help regulate body temperature, whether you are diving underwater or surfing in the wind.

When underwater, it’s important to keep your body temperature regulated. A diver wearing an extra thick winter wetsuit without underlayers can become easily exhausted. Wearing thermal layers alongside a decent, slightly thinner wetsuit should provide ample insulation, without compromising on movement or comfort.

Even on the water’s surface, wind chill can be unpleasant. When you’re constantly getting in and out of the water, thermals will provide the additional insulation necessary to keep your core temperature up.

Benefits of wearing thermals: Comfort

Wetsuit users often complain of skin chafing, abrasions, or rashes when wearing a standalone wetsuit. Salty water and smaller particles frequently get trapped between the skin and wetsuit – especially around the underarms and neck areas – causing discomfort. Thermal rash vests are designed to be comfortable, kinder on the skin, and prevent rashes from forming due to constant rubbing – hence the name.

Additional protection

Whenever prolonged exposure to the sun is a risk, a bit of protection can go a long way. Many wetsuits offer UV protection against the sun’s harmful rays. As they offer an additional layer, thermals can also help defend you from potential cuts and scrapes.

Public modesty

Changing out of a wetsuit can often involve hiding behind a towel, surrounded by spectators in a public space – a little awkward to say the least. Getting out of a wetsuit is no easy task and it requires a lot of effort to avoid being too conspicuous. Wearing thermal underlayers can therefore be a great way to change comfortably.

Pros of wearing thermals: Cost-effectiveness

Wearing fleece-lined thermal layers underneath your wetsuit will provide you with extra neoprene thickness. This will add the warmth you need, whilst allowing you to avoid the cost of purchasing a brand-new winter wetsuit.

Should I wear thermals with my wetsuit?

As with any clothing, it comes down to personal preference. If you spend a lot of time out on the water, it’s worth adding some form of thermal wetsuit clothing to your wardrobe. Being uncomfortable or freezing cold can really hinder your enthusiasm and time in the water, and it’s not uncommon for wetsuits alone to cause discomfort. Thermals are a welcome friend, offering a great solution to these problems.
