What to Wear Under a Wetsuit: A Comprehensive Guide
Choosing what to wear under a wetsuit depends heavily on factors like water temperature, the thickness of your wetsuit, and personal preference. While some people wear nothing, others find wearing a base layer crucial for comfort and warmth. Let's dive into the details.
What is the purpose of wearing something under a wetsuit?
The primary reason people wear something under a wetsuit is to enhance thermal protection. Wetsuits work by trapping a thin layer of water against your skin, which your body then warms. However, in colder water, this isn't enough, and a base layer helps to insulate further, preventing heat loss and maintaining core body temperature. Additionally, a base layer can improve comfort by providing a smoother surface against your skin, reducing chafing, and wicking away moisture.
What should I wear under my wetsuit?
The ideal undergarment depends on the conditions. Here's a breakdown:
-
Neoprene Undersuit: Specifically designed for use under wetsuits, neoprene undersuits offer excellent thermal insulation. They are made from a thinner, more flexible neoprene than a full wetsuit, making them comfortable to layer. These are great for colder water temperatures.
-
Rash Guard: A rash guard is a lightweight, stretchy garment that protects your skin from the sun, chafing, and jellyfish stings. It provides minimal insulation, making it ideal for warmer water or when using a thicker wetsuit.
-
Thermal Underwear (Long Johns): While not specifically designed for watersports, thermal underwear made from materials like merino wool or synthetic fabrics can provide warmth in colder conditions. However, be mindful that some fabrics may absorb too much water, negating the insulating properties. Look for moisture-wicking materials.
-
Nothing: In warm water temperatures, with a thick wetsuit, some people find it comfortable and efficient to wear nothing underneath. This minimizes bulk and maximizes the flexibility of the wetsuit.
Should I wear a bathing suit under my wetsuit?
Wearing a bathing suit under your wetsuit is generally not recommended. The added layer of fabric can reduce the wetsuit's flexibility and impede movement. Additionally, it adds extra bulk and may trap water, reducing insulation. Most wetsuits are designed to be worn directly against the skin, or with a specialized base layer.
What material is best for an undersuit?
Materials like neoprene, merino wool, and synthetic fabrics with moisture-wicking properties are best for undergarments. Avoid cotton, as it absorbs water, retains it, and becomes heavy and cold.
Does the thickness of my wetsuit matter?
Yes! Thicker wetsuits offer more insulation, meaning you may need less (or nothing) underneath in warmer water. Conversely, thinner wetsuits may require a base layer for adequate warmth, especially in colder conditions. Always consider water temperature as the primary factor.
What about comfort?
Comfort is key! Choose an undergarment that feels comfortable against your skin and allows for a full range of motion. Avoid anything too tight or restrictive, as this can hinder your swimming performance and cause discomfort. Consider trying out different base layers to find what suits you best.
By carefully considering water temperature, wetsuit thickness, and personal preferences, you can select the ideal undergarment to maximize warmth, comfort, and performance in the water. Remember to always prioritize safety and choose gear appropriate for the conditions.
