Wow. That is a big topic! I will try to give you an overview, but feel free to call the factory for more detail.
Most of our suits are made of some type of trilaminate material- three layers of material. The TLS350 is made of a high tenasity nylon that is very light, smooth and flexible. It is very easy to swim in while still being very abrasion resistant due to the smoothness of the material. It is used by the Navy Seals, Coast Guard Rescue Swimmers and many other dive teams for its combination of flexibility, swimmability and durability.
The FLX Extreme is also a trilaminate but it is a polyester based trilaminate which is slightly heavier than the TLS material. This type of polyester trilaminate is slightly more puncture resistant than the TLS material as well. It is our newest suit and gaining popularity and is great for people who want something light but slightly more durable than the TLS material.
The CLX is also a trilaminate but it is made of a cordura based trilaminate on the top for lots of abrasion and puncture resistance. You will lose flexibility with this suit as the cordura is somewhat stiff. It is very popular with wreck divers and underwater hunters who stick their arms into holes alot. The bottom is made of the same material as the FLX extreme in order to maintain flexibility while swimming.
The CF200 is a unique suit in that it is made of crushed neoprene. Crushed neoprene is unique to DUI and remains one of our most popular suits. It is made by taking compressed neoprene (dense neoprene), assembling the drysuit and then crushing the entire suit in a patented process. When the suit comes out of the crusher, yes we call them crushers, it is much thinner, about 2mm thick, and extremely durable. We squash all the normal bubbles in neoprene flat and thus make the material very tough against punctures and abrasion. it also will have no buoyancy as there are no more bubbles to compress and reexpand. That will also make the material very long lasting as that effect is one of the reasons wetsuits do not last very long. This material will have some warmth but very little as we have removed the bubbles from the suit. It has about a 4-6 degree insulating value over the trilaminate suits. This is the toughest suit out there and is great for people who are hard on their equipment or dive in highly abrasive environments. It will be slow to dry, heavy in comparison to trilaminate suits and will be slightly less felxible than the lighter trilaminates. However, the material does stretch and that does help compensate for it being heavier.
The FLX5050 is a hybrid suit that uses polyester trilaminate on the top for flexibilty and crushed neoprene on the bottom for durability. This suit is popular in areas where divers need to crawl over rocks to get in and out of the water- NE and NW parts of the US for example.
I hope this helps get you started. I woudl definitely recommend coming to one of our demo days sometime to try them all out. Thanks
