Dear DUI,

This is me diving at Mountain Lake in Turkey in July 2005. The altitude is 2,200 meters with a bottom temperature of 2 degrees Celsius. I was down there photographing rainbow trout.

DUI is undoubtedly the most expensive drysuit in Turkey. The reason I have one? It performs superb. Really.

As for ZipSeals, these are an incredible innovation. For someone like me, it takes a great deal of effort, time and money to plan a dive. In the past, we had to be extremely careful with our seals on a dive. The altitude and temperature makes them not very pliable. We were always very concerned about them tearing. But with ZipSeals we just carry a spare and you don't have to worry!
