What to Wear Under a Wetsuit: A Comprehensive Guide
Choosing the right undergarments for your wetsuit can significantly impact your comfort, warmth, and overall diving or watersports experience. Many factors influence this decision, from water temperature to the type of wetsuit you're wearing. This guide will delve into the common questions surrounding what to wear under a wetsuit, ensuring you're prepared for your next adventure.
What is the purpose of wearing something under a wetsuit?
The primary purpose of wearing something under a wetsuit is to improve insulation and enhance comfort. A wetsuit works by trapping a thin layer of water between your skin and the neoprene. This water is then warmed by your body heat. However, this system is only effective within a certain temperature range. Undergarments act as an extra layer of insulation, helping to retain more of your body heat and keeping you warmer in colder water. They can also improve comfort by providing a smoother surface against your skin, preventing chafing and providing a better overall fit for the wetsuit.
What should I wear under a wetsuit in cold water?
In cold water, insulation is paramount. Several options provide excellent thermal protection:
-
Neoprene Undersuits: These are specifically designed to work with wetsuits. They're made from neoprene, offering superior insulation compared to other materials. Different thicknesses are available, allowing you to adjust the level of warmth based on water conditions.
-
Thermal Underwear: Long underwear made from materials like merino wool or synthetic fleece can provide excellent insulation. Merino wool is naturally moisture-wicking, helping to keep you dry and comfortable even when you sweat. Synthetic fleece offers similar warmth without the potential for shrinkage or odor retention that some experience with wool.
-
Rash Guards: While less insulating than neoprene or thermal underwear, rash guards offer protection against chafing and sun. They're a good option for warmer water temperatures where extra insulation isn't necessary.
What should I wear under a wetsuit in warm water?
In warmer water, the focus shifts from insulation to comfort and protection. Options for warmer water include:
-
Rash Guards: A rash guard provides protection from the sun and minimizes chafing from the wetsuit. They're lightweight and allow for good freedom of movement.
-
Swimsuit or Swim Trunks: A simple swimsuit or swim trunks can be sufficient in warm water, especially if your wetsuit fits well and provides adequate protection. However, consider the level of sun protection offered by your wetsuit; if it's minimal, a rash guard or similar sun protection is still advisable.
-
Lightweight Underwear: Some divers and surfers prefer lightweight, moisture-wicking underwear for added comfort.
Do I need to wear anything under a wetsuit?
This depends entirely on the water temperature and the type of wetsuit you're using. In warmer waters, wearing nothing under a wetsuit is possible and often comfortable. However, in cold waters, wearing something underneath is crucial to prevent hypothermia. Always prioritize safety and choose appropriate undergarments based on the conditions.
Does the material of the undergarment matter?
Yes, the material of your undergarment significantly impacts its effectiveness. Avoid cotton, which retains moisture and can become dangerously cold when wet. Instead, opt for materials that are moisture-wicking, such as merino wool, synthetic fleece, or neoprene. These materials help keep you dry and warm by drawing sweat away from your skin.
What about wetsuit thickness and the choice of undergarments?
Thicker wetsuits provide greater insulation and can reduce the need for extensive undergarments in cold conditions. Conversely, thinner wetsuits will benefit from additional thermal protection provided by undergarments. Choosing the right combination of wetsuit thickness and undergarment will help ensure you stay warm and comfortable throughout your activity.
By carefully considering water temperature and wetsuit type, you can select the appropriate undergarments to maximize your comfort and safety in the water. Remember, it's always better to err on the side of caution, especially in colder water conditions.
