What to Wear Under a Wetsuit: A Comprehensive Guide
Choosing the right underlayer for your wetsuit can significantly impact your comfort, warmth, and overall diving or watersports experience. Whether you're surfing frigid Pacific waves, diving in a cool lake, or kayaking in chilly waters, understanding what to wear beneath your wetsuit is crucial. This guide will cover everything you need to know, answering common questions and helping you select the perfect base layer.
What is the purpose of wearing something under a wetsuit?
The primary purpose of wearing something under a wetsuit is to trap a thin layer of water between your skin and the neoprene. This water layer is then warmed by your body heat, creating insulation. Wearing something too thick can actually hinder this process by reducing the water's ability to warm up. The underlayer also provides an added layer of comfort and protection against chafing from the wetsuit itself.
What type of clothing should I wear under a wetsuit?
The ideal underlayer depends on the water temperature and the thickness of your wetsuit. Generally, you should prioritize moisture-wicking fabrics. Materials like:
- Synthetic materials (polyester, nylon): These fabrics excel at pulling moisture away from your skin, keeping you dry and preventing chills.
- Merino wool: Offers excellent insulation and moisture-wicking properties, even when wet. It's naturally antimicrobial, reducing odor build-up.
Avoid wearing cotton, as it retains moisture and will make you feel cold and uncomfortable.
Should I wear a rash guard under a wetsuit?
Rash guards are a popular choice as an underlayer, especially for warmer water temperatures. They provide sun protection, a smooth surface to minimize chafing, and a slight layer of warmth. However, for colder water, a rash guard alone may not provide sufficient insulation.
What should I wear under a wetsuit in cold water?
For cold water, consider layering:
- A thin thermal base layer: Opt for a lightweight long-sleeve top and bottom made from a moisture-wicking material like polyester or merino wool.
- Neoprene inner layer: A thin neoprene top or fullsuit can add significant warmth for very cold water conditions.
What about wearing thermal underwear under a wetsuit?
While thermal underwear might seem like a good idea, it's generally not recommended under a wetsuit. The bulkiness can restrict movement, reduce flexibility, and prevent the proper insulation of the water layer. As mentioned, a thin, form-fitting layer is far more effective.
Can I wear swimwear under a wetsuit?
Swimwear can be worn under a wetsuit, particularly in warmer water, but it offers minimal insulation and less protection against chafing than other options. A rash guard or thin thermal base layer would be preferable.
What should I avoid wearing under a wetsuit?
As emphasized previously, avoid cotton at all costs! Also avoid:
- Thick, bulky clothing: This will hinder movement and prevent the water from warming properly.
- Rough or scratchy fabrics: These can cause chafing and discomfort inside the wetsuit.
By carefully considering these factors and selecting the right underlayer, you can ensure a comfortable, warm, and enjoyable experience in the water, no matter the conditions. Remember to prioritize moisture-wicking materials and choose layers that are thin and form-fitting to maximize the wetsuit's insulating properties.
