The most important difference between a suit that is wet and one that is dry is how much water can be allowed to pass through the suit. Your personal preference and your plans for participation will determine which wetsuit you choose. Ask yourself questions like how long you plan to be in the water, how cold it gets, and what your body type is.
Gore-Tex dry suits
Fabric is a major difference between GoreTex dry suits versus wetsuits. Non-Gore-Tex dry suits don't breathe as well and don't offer the same level of durability and comfort. There are new dry suit fabrics, including waterproof and breathable fabrics. Kokatat, for example, designed a dry suit made of a durable, yet breathable Gore-Tex fabric. Kokatat was the first person to develop and introduce suits to the market.
Trilaminate dry suits
The outer shell of each suit is what distinguishes wet suits from dry suits. Trilaminate suits can be waterproof, but they don't have insulation and are usually lightweight. They are also less flexible than trilaminate suits and must be properly fitted. This article will discuss the differences between trilaminate and wet suits, and give tips for choosing which suits you best.
Hydrus 3L fabric dry suit
The Kokatat Hydrus 3L has been updated to replace the T3 Swift Entry. It is made from water-resistant, breathable and three-layer fabrics. Its tough nylon outer layer and proprietary polyurethane micro-porous inner coating both move water vapor away from your body, while the soft knit polyester inner layer is comfortable against your skin. This drysuit comes with tough latex neck-, wrist-, and ankle gaskets to keep water from entering.
Hydrus 3L fabric suits from Kokatat and Stohlquist
The Kokatat Hydrus 3L Meridian drysuit is ideal for those who want to swim comfortably and stay warm. The suit has a drop-seat, a hood and Cordura(TM), panels to keep you warm from the cold. The suit comes with adjustable legs and waterproof and breathable sock. You can also adjust the bungee waistcord for a more snug fit.
IR's suits
A wetsuit is more durable than a drysuit when it comes to keeping you dry. Dry suits keep you warm and prevent water from reaching your body. Many dry suits have purge valves. Dry suits are a common choice for aircrews.
