RST S1 Giacca in pelle moto

Here to help others to find the right size.

I'm 183cm / 6 ft,
90 kg/ 200 lbs,
chest 115 cm/ 46",
waist 94cm / 37".
Athletic build.
Normal jacket size 54 or usually 56 (from L to XXL) depending on the manufacturer. Alpinestars GP Pro plus v4 in size 54 is very snug but doable for me. A race fit for sure.

So, according to RST size chart, I would be dead on with 46/56 size jacket. And based on the majority of the reviews online I would be better of by going size up to 48/58.

Despite all these, I went with the size 44/54. Is not too tight. Close to race fit, but I believe I can still squeeze in some sort of (thin)midlayer (haven't tried it yet though) and this is with Alpinestars Plasma back protector and the quilted thermal vest.
I guess I could do with a 46/56 jacket, but I like these type of jackets close fitting. 48/58 would be way too big, take my word for it.

If you like your leathers flapping around in the wind, go right ahead and go one size up. That is not my advice to you unless you have very sizeable mid section and unnaturally broad back.
This jacket has more room especially for the arms than Alpinestars.

I have not riden with the jacket yet, since we have snow and ice until late april. Just here to let you know of the fit.
Hope this helps.
