Size is EU54/US44. It fits too big for me. It was a gift and I can not return it. Only worn once inside. Still has the tags and will be shipped in the plastic it came with. Tech Air Compatible with all of Alpinestars Airbags. STG sells this suit for $1850 plus tax. It can be yours for $1500 shipped inside the US from the MD/VA area.
I’m 5-9 175 lbs. fits ok in the chest and shoulders with the tech air but I have no ass or legs so it’s way loose everywhere else on me.
