Dear DUI,

Norbert WU and I are here in Antarctica filming for the BBC's latest blockbuster natural history series, LIFE. This is the third series in a trilogy that started with Blue Planet and Planet Earth.

Diving in the 28 degree water here is amazing. It is also the coldest water in the world, and is super-cooled due to the water flowing from under the Ross Ice Shelf to our dive sites.

We chose the best gear for this project, obviously. Norb and I are both diving the DUI TLS350, an amazing drysuit with total reliability, great fit, and wonderful flexibility. The suit is perfectly fitting and made to last. We LOVE our DUI's.
