Horrible fit, but amazing jacket - Mammut Nordwand Pro Hard Shell Hooded Jacket - Men's

So this jacket ticks all the boxes. Best materials, looks awesome, great pockets, pit zips, hood works in all situations with and without helmets BUT...and this is a biggie. The size is strange!!!
I'm 6'2'' and long arms, narrow shoulders 170 lbs 38 inch chest.
I bought a large.
It binds in the arm pits and at the elbows with just a baselayer and fleece or nano air on. If just a baselayer it is fine.
The body seems very large, if you have a potbelly you're good. The chest seems tight though. size chart says this should be like a 40-43inch chest.
The arms are a great length though.
I'm too skinny to want to try an XL...I think the hood and collar would be like the cone of shame and I don't want to wait, try it on and then send back in for something else.

good luck!
