I do like the design, it evokes the ideas of 'Walkabout' and 'Dreamtime' which link to the hermit traditions of the Abrahamic religions. I've alluded to Christ's forty days in the wilderness elsewhere.
I recall a conversation with a US rider in 2003, somewhere around Uzel, in the dark. He told us of his time in Vietnam, and his struggles since then, moving from job to job. How he'd ridden PBP twice, but not finished it. He seemed to be searching for some form of redemption. It was tempting to reach out and help him achieve his dream. He then asked if we'd seen the thousands of butterflies which surrounded a passing car. We quietly upped our pace, and rode off. That jersey design brings that to mind.
When someone asks, "What's it like to ride 1200km in all terrain and weathers, with three hours sleep?" I could say "It's like this jersey". I'll be surprised if anyone gets back to Oz without having swapped it.
