Latex or Silicone? What Is The Best DUI Zipseals For Me?

Good question! With the innovation of using silicone for drysuit seals and now DUI Zipseals, there are many who think this is the ultimate seal for them.
What is the difference now?

The biggest advantage of silicone seals is the high resistance to UV and ozone. According to the divers who dive with DUI Silicone Zipseals, they offer more comfort and prevent more leaks at the wrist seals. Silicone is ideal for divers with an allergy to latex.
The disadvantage of silicones is that they tear more easily when they come into contact with sharp objects and must be handled with more care. Silicone also tends to attract dust, but the material does not decay.
