Waterproof wrist seal
For too long, latex seals have been the biggest problem in drysuit diving. You never know what condition they'll be in until you open your dive bag. They are easy to tear and deteriorate due to factors such as sun/UV rays, chemicals and ozone. Silicone gaskets raise the bar, as they are not vulnerable to most chemicals or the environment and their elasticity is 40% higher than latex gaskets. The elasticity makes donning much easier and minimizes the risk of water infiltration. Since the pressure is lower on the wrists, your hands will stay warmer. Comfort is really improved during long technical dives and decompression stops.
