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, and personal preference. There's no one-size-fits-all answer, but understanding the options and their benefits will help you stay comfortable and warm during your water activities. This guide will explore the various choices and address common questions surrounding this topic.
What is the purpose of wearing something under a wetsuit?
The primary purpose of wearing something under a wetsuit is insulation. Wetsuits work by trapping a thin layer of water between your skin and the neoprene. This water is heated by your body, creating a layer of insulation. However, in colder water, this layer isn't enough. Wearing a base layer adds another layer of insulation, trapping more heat and keeping you warmer for longer. A secondary benefit is enhanced comfort; some find certain fabrics softer and more comfortable against their skin than neoprene alone.
What are the best materials for base layers under wetsuits?
Several materials excel as base layers under wetsuits, each with its own advantages:
-
Neoprene Undersuits: These are wetsuit-like garments made from thin neoprene. They offer excellent insulation and flexibility, often with a smoother inner lining for enhanced comfort against the skin. They're a good choice for colder water temperatures.
-
Synthetic Materials (Polyester, Nylon, Polypropylene): These wick away moisture, keeping you dry and preventing chafing. They are lightweight and fast-drying, making them ideal for warmer water or shorter sessions. Look for fabrics specifically designed for water sports.
-
Merino Wool: Known for its excellent insulation and natural odor resistance, merino wool provides warmth even when wet. It's a good choice for colder conditions but can be more expensive than synthetics.
-
Rash Guards: These are typically made from lightweight, stretchy materials like lycra or spandex. They mainly offer sun protection and prevent chafing but provide minimal insulation. They're great for warmer water and activities where minimal bulk is desired.
Should I wear a swimsuit under my wetsuit?
Whether or not you wear a swimsuit under your wetsuit depends on your personal preference and the thickness of your wetsuit. For thinner wetsuits, a swimsuit underneath can offer extra warmth and modesty. However, with thicker wetsuits (e.g., 5mm+), a swimsuit may be unnecessary, adding extra bulk and potentially reducing flexibility.
What should I wear under a wetsuit in cold water?
In cold water, maximizing insulation is key. A neoprene undersuit or a merino wool base layer is highly recommended. Layering might be beneficial, depending on the water temperature and your personal tolerance for the cold. Always check water temperature forecasts before your session.
What should I wear under a wetsuit in warm water?
In warm water, your primary concern is likely comfort and sun protection. A rash guard or a lightweight synthetic base layer is usually sufficient. Avoid overly thick materials to prevent overheating.
Does the type of wetsuit affect what I wear underneath?
Yes. Thicker wetsuits generally require less additional insulation than thinner wetsuits. Full-body wetsuits might require a full-body base layer for optimal warmth, while shorty wetsuits might only need a rash guard or a top and bottom set.
In summary, selecting the right underlayer for your wetsuit is crucial for comfort and warmth. Consider the water temperature, wetsuit thickness, and the activity duration when making your choice. Experimenting with different base layers will help you find the perfect combination for your needs.
