I did a century in moderate to heavy rain in this get up (minus the gilet) a couple of weekends back and it was, as it always is, perfect. The thing that always impresses is the temperature regulation. Never too hot, never too cold. Which is my problem with the PTJ. It has to be down to 5 degrees and under for it to be comfortable. I barely wore it last year.
TLDR - The Gabba is the most versatile bit of kit I own. Worth every penny.
