What to Wear Under a Wetsuit: A Comprehensive Guide
Choosing what to wear under a wetsuit depends heavily on several factors: water temperature, wetsuit thickness, personal preference, and the type of activity. While some people dive straight in wearing nothing but their swimsuit, others prefer layering for extra warmth and comfort. This guide will explore the various options and help you decide what's best for you.
What is the purpose of wearing something under a wetsuit?
The primary reason to wear something under a wetsuit is insulation. A wetsuit works by trapping a thin layer of water against your skin. This water is warmed by your body heat, creating a layer of insulation. However, in colder water, this insulation might not be enough. Adding a base layer can significantly improve your warmth and comfort. Beyond warmth, some people also appreciate the added comfort and protection against chafing that a base layer provides.
What are my options for base layers under a wetsuit?
You have a variety of options for what to wear underneath a wetsuit, each with its own advantages and disadvantages:
-
Swimsuit or Bathing Suit: This is the simplest option, often sufficient for warmer water temperatures and thinner wetsuits. It provides minimal insulation but avoids bulk.
-
Rash Guard: A rash guard is a lightweight, usually spandex-based shirt designed to protect against sun, wind, and chafing. It offers minimal warmth but can be a good choice for warmer waters or as an extra layer of sun protection.
-
Neoprene Undersuit: Made from neoprene, just like wetsuits, these offer excellent insulation and are specifically designed to be worn under wetsuits. They come in various thicknesses, allowing you to adjust the level of warmth.
-
Thermal Underwear: While not specifically designed for watersports, thermal underwear made from materials like merino wool or synthetic blends can provide additional warmth. However, these can sometimes feel bulky under a wetsuit.
What thickness of wetsuit do I need?
The thickness of your wetsuit will significantly impact what you need to wear underneath. Thicker wetsuits offer more insulation, meaning you may need less, or even nothing, underneath in cold water. Thinner wetsuits, on the other hand, may require a base layer, especially in colder conditions.
What material is best for a base layer under a wetsuit?
Materials like neoprene, merino wool, and synthetic fabrics are popular choices for base layers worn under wetsuits. Neoprene provides superior insulation. Merino wool offers excellent warmth and moisture-wicking properties, while synthetic fabrics are often more durable and quicker-drying. Avoid cotton, as it retains moisture and can become cold and heavy when wet.
Does wearing something under a wetsuit affect its fit?
Yes, wearing a base layer will change the fit of your wetsuit. A thicker base layer will make your wetsuit feel tighter. It's important to choose your base layer carefully to ensure a comfortable and functional fit. Consider trying on your wetsuit with your intended base layer to check the fit before you commit to a dive or water sport activity.
Should I wear anything under a wetsuit in warm water?
In warm water, you may find a simple swimsuit or nothing at all is sufficient. However, a rash guard can offer sun protection and minimize chafing. The best choice depends on your personal preference and the level of activity.
Ultimately, the best choice of what to wear under your wetsuit depends entirely on individual needs and conditions. Experiment to find what works best for you to ensure maximum comfort and warmth during your watersports activities. Prioritize safety and comfort above all else!
