Selecting the right wetsuit is crucial for comfort and performance in the water. Wetsuit thickness is a primary factor, directly impacting warmth and flexibility depending on water temperatures. This guide will help you understand how to choose the ideal wetsuit based on water temperature and seam construction.
Understanding Wetsuit Thickness for Water Temperatures
Wetsuit thickness, measured in millimeters (mm), ranges from thin 0.5mm suits for warm tropical waters to thick 7mm suits designed for frigid conditions. The optimal thickness depends heavily on the average water temperature you’ll be surfing or participating in water sports in.
For example, in regions like Southern California, summer water temperatures average in the high 60s Fahrenheit (around 20°C). During these warmer months, surfers often opt for short-sleeve full wetsuits, spring suits, or even just wetsuit jackets. However, as fall transitions into winter and water temperatures drop to the mid-50s Fahrenheit (around 12-13°C), switching to 3/2mm or 4/3mm full wetsuits becomes essential for maintaining warmth.
Having a selection of wetsuits with varying thicknesses is advisable, especially if you surf in a location with significant seasonal temperature changes. This ensures you’re adequately protected and comfortable throughout the year.
Wetsuit Seam Types and Their Impact on Warmth
The seams of a wetsuit, where neoprene panels are joined, are critical to its overall performance. Seams are designed to minimize water entry, but different seam constructions offer varying degrees of water sealing, flexibility, and warmth.
Flatlock Seams: For Warm Water
Flatlock seams are commonly found in wetsuits designed for warmer waters. These seams are created by overlapping and stitching the neoprene panels together, resulting in a durable and flexible seam. While comfortable and breathable, flatlock seams are not watertight and allow some water exchange. This makes them suitable for warmer conditions where maximum warmth retention is not the primary concern.
Glued and Blindstitched (GBS) Seams: Enhanced Water Sealing
Glued and Blindstitched (GBS) seams offer a significant step up in terms of water sealing. In GBS construction, the neoprene edges are first glued together and then blindstitched. Blindstitching means the needle doesn’t fully penetrate the neoprene, creating a watertight seam. GBS seams minimize water entry, providing better warmth in cooler conditions compared to flatlock seams. Reinforcement with internal neoprene tape is often added to high-stress areas for increased durability.
Liquid Sealed and Taped Seams: Maximum Warmth for Cold Water
For the coldest water temperatures, liquid sealed and taped seams are the premium choice. In this construction, after the panels are glued and blindstitched, the exterior seam is sealed with a liquid rubber or silicone-based sealant. This creates a robust, watertight barrier that significantly reduces water entry and maximizes warmth. Internal sealed neoprene tape is also applied for added reinforcement and longevity. Wetsuits with liquid sealed seams are ideal for surfers and water sports enthusiasts facing very cold water conditions.
Choosing the right wetsuit involves considering both the thickness appropriate for your typical water temperatures and the seam type that best suits the conditions and your budget. By understanding these factors, you can ensure a comfortable and enjoyable experience in the water, regardless of the season.
