The Castelli Perfetto range seems well reputed and Wiggle are having a sale on the convertible jackets at the moment. Sizes available are:
* Blue: Small, Medium, Large
* Red: Small, Medium
Local RRP is $299.
General consensus around sizing appears to be to size up 1 size from what you would wear normally.
Don't forget Cashrewards 2.80%.
I thought this jacket was for Wiggles, rather than from Wiggles
