Buying Guide for Open Water Swimming Wetsuits
Selecting the right wetsuit for open water swimming involves evaluating various factors to meet your specific needs.
Thickness and Warmth
Wetsuit thickness, typically between 2mm and 5mm, determines thermal protection. Thicker neoprene provides more warmth but can reduce flexibility. For moderate conditions, 3/2mm suits strike a good balance. In warmer waters, thinner 2mm suits or shortys are suitable, while colder environments require thicker options.
Fit and Flexibility
A snug fit that minimizes water flushing is critical. Look for designs facilitating a full range of motion, especially around the shoulders and neck, to allow comfortable stroke extension. Stretchy neoprene fabrics and flatlock or blind stitch seams enhance flexibility and comfort.
Buoyancy and Panel Placement
Buoyancy panels placed on the chest and core help maintain optimal swimming position and improve efficiency. Consider suits incorporating a 3mm buoyancy core with thinner limb panels to assist movement while providing flotation.
Seams and Zippers
Seam types—flatlock for durability & comfort or blind stitched & taped for high-end water resistance—impact warmth and durability. Internal zippers, usually YKK brand with anti-corrosion treatment, reduce drag and increase lifespan. The location (back vs. front) can affect ease of putting on and taking off the suit.
Design and Additional Features
Look for smoothskin panels that reduce wind chill and surface drag as well as low collar designs which prevent neck chafing. Some suits also offer UV protection. Consider whether sleeveless, full sleeve, or shorty suits best suit your activity and water conditions.
Durability and Care
Invest in well-constructed suits using high-quality neoprene and durable stitching. Proper care including rinsing after use and storing away from direct sunlight prolongs the life of the wetsuit.
Considering these factors will help you select a wetsuit that offers warmth, buoyancy, and freedom of movement so you can enjoy safe and productive open water swimming.
