Choosing the right undergarments for your wetsuit can significantly impact your comfort, warmth, and overall diving or watersports experience. Whether you're a seasoned pro or a beginner, understanding what to wear beneath your wetsuit is crucial for maximizing performance and minimizing discomfort. This guide will delve into the various options, helping you select the perfect base layer for your next adventure.
What is the purpose of wearing something under a wetsuit?
The primary purpose of wearing something under your wetsuit is to enhance thermal insulation. Wetsuits work by trapping a thin layer of water between your skin and the neoprene. This water warms up to your body temperature, providing insulation. However, wearing a base layer can improve this insulation further, especially in colder water. A good base layer will also wick away moisture from your skin, keeping you drier and more comfortable.
What are the different types of undergarments for wetsuits?
Several options exist, each with its own advantages and disadvantages:
1. Rash Guards:
These are thin, lightweight shirts made from a stretchy, quick-drying fabric like polyester or spandex. Rash guards primarily protect your skin from chafing against the wetsuit's seams and provide a small degree of sun protection. They offer minimal insulation but are excellent for warmer water temperatures.
2. Thermal Underwear (Long Underwear):
These come in various thicknesses and materials, from lightweight merino wool to heavier fleece or synthetic blends. They provide significantly more insulation than rash guards, making them suitable for colder water. Look for moisture-wicking fabrics to prevent overheating and retain dryness.
3. Neoprene Undersuits:
These are essentially thinner wetsuits worn under your main wetsuit. They offer excellent insulation and are designed to trap a layer of warm water close to your body. Neoprene undersuits are ideal for extremely cold water conditions but can be bulky and less flexible than other options.
4. Merino Wool Base Layers:
Merino wool is a natural fiber known for its excellent warmth-to-weight ratio, moisture-wicking properties, and odor resistance. Merino wool base layers are a great choice for colder water temperatures, providing warmth without excessive bulk. They are also naturally antimicrobial, reducing odor buildup.
What should I consider when choosing an undergarment?
Several factors influence your choice:
- Water Temperature: The colder the water, the more insulation you'll need. Rash guards are fine for warm water, while thermal underwear or neoprene undersuits are better for cold water.
- Activity Level: High-intensity activities generate more body heat, potentially making thicker layers unnecessary. For less strenuous activities, more insulation may be preferable.
- Wetsuit Thickness: A thicker wetsuit will already provide more insulation, potentially reducing the need for a thick undergarment.
- Personal Preference: Some people prefer the feel of certain materials over others. Experiment to find what's most comfortable for you.
What should I NOT wear under a wetsuit?
Avoid wearing cotton under a wetsuit. Cotton absorbs water and takes a long time to dry, leaving you cold and uncomfortable. This can even lead to hypothermia in cold conditions.
How do I care for my wetsuit undergarments?
Proper care will extend the lifespan of your base layers. Always rinse your undergarments thoroughly with fresh water after each use to remove salt and chlorine. Follow the manufacturer's instructions for washing and drying; generally, air drying is preferred to prevent damage from high heat.
By carefully considering these factors and selecting the appropriate undergarments, you can ensure a comfortable, warm, and enjoyable experience in the water, regardless of the temperature. Remember, layering is key – you can always add or remove layers as needed to maintain optimal comfort.
