Leather Alpinestar Jacket fitness?

Hi, today I purchased an "Alpinestars Jaws Leather Jacket" plus gloves and helmet from a friend and was wondering about "correct" sizing of the jacket.

First of the I am around 5 feet 5 inches (168cm )and 155 ~ 160 pound guy. When I measured by body sizing with the template offered by the Revzilla, I was in the medium ~ large size (39.5 inches chest) (40/50), whereas the one I got from my friend is around large ~ X large (48/58). Now that I have tried on the jacket and it was very comfortable, with little bit of room inside the jacket (once it is zipped up). But the bottom opening of the jacket seemed a bit open. Will this be a problem once I start riding on a motorcycle (total beginner)? Or I shouldn't worry about it?

Also, if this is a bit large, is there a way to shrink down the jacket to more suitable size? or try to bulk up so the muscle mass would compensate for the extra room (plausible?)

hey sam. i am probably about ur size 5.6 155. I dont have the jaws but i do have the alpinestars GP Plus perforated one. and its very similar i have a size 40 US(50EU).

I recommend visiting your local motorcycle gear store and try jackets sizes. went i went I try the 42 US and it was a bit to big not very compressed and bit open in the bottom section.
40 was the right fit for me. but like i said try maybe a medium or small depends on your chest and arm length.

In a crash, a jacket that is to large can ride up on your body. It probably doesn't happen to often, but it is something to be aware of. I would be more worried about how the helmet fits though.

Helmets need to be snug. You should not be able to move it around to much when it is strapped on. If you can shake your head back and forth and the helmet moves on your head, it is to big.

Thank you so much for buying gear first and motorcycle second!

I thought maybe I could wear layers to make it more tight, but definitively the helmet is a very good fit. Without the strap it "snaps" in place, I would try all sort of crazy motion to knock it out, but it stays very firm.

And of course, safety is always #1 priority of me, because I was able to convince my family for me to get a bike.

To me was said from the Dealer when i Trier tue Jackets i should buy EU 38 cause EU 40 seems like to big for the shop Assistent, but fo me the bigger one was much more suitable than the tight one, i think i will grow also a little bit. I am 18y young... Haha
I love alpinestars.

Gloves: GP Plus, Size: L
Jacket: GP Plus R Perforated, Size: EU40

Still asking myself which Boots and down part thing... Whatever it is called to buy hahaha
I have 38.5 chest and I bought 50euro size, turns out it was too big and I had to downsize to 48euro.
I can't imagine how you can ride comfortably on a jacket 4 sizes too big :)
