Does the medium fit into an Alpinestars GP-R Perf size 48?
I would assume the size 48/ (38 US) is a small but I can only find the bionic back in medium and large.
5'10" and the 48 fits great.
I have a size 46 ero Alpinestars GP-R Perf. The foam that comes in the jacket measures 19in tall, where the MD back proctector measures 16in tall. See pic for clarification.
