The CF200SE drysuit by DUI. The legend continues in a more streamlined, shoulder entry design. Only DUI has crushed neoprene! We take 3mm neoprene and put the material through a process which it actually off-gases and crushes it to about 1mm. This makes a very dense, stretchy material that offers the ultimate in protection from the environment. The CF200 is the choice for wreck and commercial divers and those that want a drysuit that is virtually bulletproof.
