The primary difference between a wetsuit and a drysuit, is how much water is allowed into the suit. It is up to you and the activities that you are going to be participating in that will decide if you want a wetsuit or a drysuit. Ask yourself questions about how long you intend to stay in the water, how cold it gets and what your body type.
Dry suits made of Gore-Tex
Fabric is a key distinction between GoreTex dry suits, and wetsuits. Non-Gore-Tex dry suits don't breathe as well and don't offer the same level of durability and comfort. New dry suit fabrics are available, including waterproof and breathable fabric. Kokatat, for example, designed a dry suit made of a durable, yet breathable Gore-Tex fabric. Kokatat's suits are the first to have been developed and put on the market.
Trilaminate dry suits
The basic difference between wet suits and trilaminate dry suits is the material used for the outer shell of each suit. Trilaminate suits are waterproof but lack insulation. They are also lightweight. They also require a better fitting and are less flexible that trilaminate ones. This article will discuss the differences between trilaminate and wet suits, and give tips for choosing which suits you best.

The Kokatat Hydrus 3L is the updated version of the T3 Swift Entry, and is made from a water-resistant, breathable, three-layer fabric. The outer nylon layer and the proprietary polyurethane microporous inner coating move water vapor away. While the inner layer of soft knit polyester is comfortable against your skin, it has a tough nylon layer. This entry-level drysuit also features a tough latex neck, wrist, and ankle gaskets to keep water out.

Suits of IR
If you are comparing the advantages of a wet suit and a drysuit, remember that they both have waterproof and watertight properties, which means they can keep you dry longer. Dry suits are not only warm but they also keep water from transferring onto your skin. Purge valves are also common in dry suits. Dry suits are a common choice for aircrews.
