After much deliberation I finally ordered my jacket on line from Urban Rider. I called the store direct from Australia to confirm fit and sizing. I finally decided to go with the XL. I'm glad I did as the jacket fits perfectly. For reference I'm 178cm, 82 kgs, chest is 104cm, 35" in waist. Be aware that this jacket is a slightly slimmer fit, IMHO going down to a large would have been too tight, especially if you plan to wear the inner liner and some layers in the colder months, also worth noting that the arms are tight and the extra arm liner is not removable. The jacket itself is of great quality and heavier than expected. As other reviews have stated the armour is easily removed allowing the jacket to be worn more casually. Finally, big thanks to Urban Rider, great over the phone service and the free delivery is amazing. Seriously, ordered 8.30 pm Friday night, delivered to my front door in Australia 11.30 am Tuesday morning.
