What to Wear Under a Wetsuit?

Choosing the right underlayer for your wetsuit can significantly impact your comfort and performance in the water. The ideal underlayer depends on several factors, including water temperature, wetsuit thickness, and the type of activity. Wearing the wrong thing can lead to discomfort, chafing, or even hindering your performance. This comprehensive guide will help you choose the perfect base layer for your next aquatic adventure.

Understanding Wetsuit Function

Before diving into underlayer options, let's briefly discuss how wetsuits work. Wetsuits create a thin layer of water between your skin and the neoprene. Your body heat warms this water, providing insulation. A good underlayer can help maintain this warmth and minimize heat loss.

Types of Underlayers for Wetsuits

Several different types of clothing can be worn under a wetsuit, each with its own benefits and drawbacks. Let's explore the most popular options:

1. Rash Guards

What they are: Lightweight, usually made from lycra or polyester, rash guards primarily protect your skin from chafing against the wetsuit's seams. They offer minimal insulation.
When to use them: Ideal for warmer water temperatures or when you need sun protection. Great as a single layer in warm conditions or as a base layer under other garments.
Pros: Lightweight, quick-drying, protects against sun and chafing.
Cons: Minimal insulation.

2. Thermal Underwear

What they are: Made from various materials like fleece, polypropylene, or merino wool. These provide significant insulation and moisture-wicking properties.
When to use them: Best for colder water temperatures, offering enhanced warmth under your wetsuit.
Pros: Excellent insulation, wicks away moisture, comfortable.
Cons: Can be bulky, may restrict movement if too thick.

3. Neoprene Undersuits

What they are: Made from thin neoprene, these mimic the feel and function of a wetsuit but in a thinner, more flexible layer.
When to use them: Ideal for colder conditions, offering superior insulation compared to rash guards and thermal underwear.
Pros: Excellent warmth, good flexibility, seals in body heat.
Cons: Can be expensive, potentially restricts movement depending on thickness.

4. Swimsuits/Swim Trunks

What they are: Standard swimwear provides minimal protection but is suitable for warm water.
When to use them: Appropriate only in very warm water where insulation isn't necessary. Offers less protection against chafing compared to rashguards.
Pros: Lightweight, familiar feel.
Cons: Provides minimal insulation, may chafe against the wetsuit.

Choosing the Right Underlayer: Factors to Consider

Water Temperature: The colder the water, the more insulation you'll need. For warmer water, a rash guard may suffice. Colder water calls for thermal underwear or a neoprene undersuit.
Wetsuit Thickness: A thicker wetsuit will generally offer more insulation, so you may need less underlayering. Thinner suits require additional layers for warmth.
Activity Level: More strenuous activities generate body heat, so you may need less insulation than for passive activities.
Personal Preference: Consider your comfort level. Some people prefer a snug fit, while others prefer more room.

Layering Techniques

For optimal warmth in colder conditions, layering can be highly beneficial. Consider layering a lightweight thermal base layer under a thicker thermal layer or a neoprene undersuit. Avoid bulky layers that restrict movement or reduce flexibility.

Maintaining Your Underlayers

Proper care of your underlayers will prolong their lifespan. Always rinse your underlayers with fresh water after each use to remove salt and chlorine. Follow the manufacturer’s instructions for washing and drying.

Conclusion

Selecting the right underlayer for your wetsuit is crucial for a comfortable and successful water experience. By considering water temperature, wetsuit thickness, activity level, and personal preference, you can ensure you're optimally prepared for your next adventure. Remember to always prioritize comfort and safety—a well-chosen underlayer can make all the difference!
