Australian conservationist and TV personality Robert Irwin fronts the latest campaign for Columbia Sportswear, following his appointment as a brand ambassador last year.

Irwin commented 'I never thought I'd be outrunning dozens of crocodiles in the middle of the Aussie outback. I've been putting Columbia's gear to the test my entire life, so when they asked me to help show how it holds up through my unexpected adventures, I was all in'.
