just measured and it's around 24.5"p2p give or take a little. Padded, and lined so fit's abit smaller than this. Tried it on today after getting it and it's abit big.
All yours for the small price of £60, bare in mind delivery will be around a tenner, due to the weight and size of the jacket. Will also accept sways or PX etc. 22"p2p on jackets.
