What to Wear Under a Wetsuit: A Comprehensive Guide
Choosing what to wear under a wetsuit depends heavily on water temperature, the type of wetsuit you're using, and personal preference. There's no one-size-fits-all answer, but this guide will break down the options and help you find the best solution for your needs. Ignoring this crucial aspect can lead to discomfort, reduced performance, and even hypothermia in cold water.
What's the Purpose of Wearing Something Under a Wetsuit?
The primary goal of wearing something under a wetsuit is to create a layer of insulation, trapping a thin layer of water between your skin and the neoprene. This water is warmed by your body heat, creating a thermal barrier against the cold water surrounding you. However, wearing too much can restrict movement and make the wetsuit less effective.
What should I wear under a wetsuit in cold water?
This is a critical question. In truly cold water (below 10°C/50°F), you'll need more insulation than just a wetsuit. Several options exist:
-
Neoprene Undersuit: These are specifically designed to work with wetsuits, offering excellent thermal properties and flexibility. They are made from thinner neoprene than a full wetsuit, allowing for ease of movement without sacrificing warmth. They come in various thicknesses, so choose one appropriate for the water temperature.
-
Rash Guard & Neoprene Leggings: A combination of a long-sleeve rash guard and neoprene leggings provides a good balance of warmth and flexibility. The rash guard protects your skin from chafing and provides a slight layer of warmth, while the leggings focus insulation on your lower body, which is often more susceptible to cold.
-
Thermal Underwear: While technically possible, thermal underwear made from materials like merino wool or polypropylene is generally less ideal than purpose-built neoprene undersuits. These can retain moisture, leading to discomfort and a loss of insulation. However, in milder conditions, they might be suitable for some.
What should I wear under a wetsuit in warm water?
In warmer waters (above 15°C/59°F), you may not need anything under your wetsuit. However, some people prefer wearing:
-
Rash Guard: A rash guard primarily provides protection against sunburn, chafing, and minor abrasions from the wetsuit. It's lightweight and breathable, making it comfortable in warmer temperatures. It can also slightly improve the fit of the wetsuit, preventing it from slipping.
-
Swimsuit or Board Shorts: These are acceptable, mainly for modesty, but they add little in terms of thermal protection.
What about wearing a swimsuit under a wetsuit?
Wearing a swimsuit under a wetsuit is acceptable and often recommended for hygiene purposes. A swimsuit provides a layer between you and the neoprene, making it easier to keep the wetsuit clean. It also serves as a base layer, enhancing comfort. However, it doesn't provide significant thermal insulation.
Should I wear anything under a dry suit?
Dry suits are designed to be completely waterproof, keeping you dry from the outside elements. Under a dry suit, you'll typically wear:
-
Thermal Underwear: This is crucial for insulation in cold water and cold air conditions. Multiple layers of thermal underwear are often needed for the best protection.
-
Drysuit Underwear: Similar to neoprene undersuits for wetsuits, specialized drysuit underwear is available for enhanced warmth and comfort.
Choosing the Right Undergarment: Key Considerations
- Water Temperature: This is the most significant factor. Colder water necessitates more insulation.
- Wetsuit Thickness: A thicker wetsuit generally needs less additional insulation.
- Activity Level: More strenuous activities may require less insulation as your body generates more heat.
- Personal Preference: Some people are more sensitive to cold than others, leading to individual needs.
By carefully considering these points, you can find the perfect combination of warmth, comfort, and movement to maximize your enjoyment in the water. Remember, proper layering is key to a safe and enjoyable experience.
