Hi Alessandro,
I have similar measurements as you, 194 cm with a long back and long arms, although I have a more muscular build, and while probably nobody would call me overweight, as I creep past 50 years old, I can no longer describe myself as "skinny"
I have tried many jackets in XL.
I just bought and returned a Tupilak because it was too short in the hem. This was very dissapointing becasue in many other respects I really like dthe jacket.
Arcteryx sometimes works depending on the model. The Alpha models work. They are expensive, but in my experiece they truly are a higher level of quality, ad hence perhaps a good value.
The Patagonia Triolet is acceptable (longer than the Tupilak) but the cut and details are not ideal in other ways.
The new Super Alpine is no longer than the Triolet, and has some anoying details.
The longest jacket I have found so far is the Patagonia Dual Aspect. It has a really nice face fabric and a great feel. The helmet fits nicely over a hood. It's the best I've found for me.
Of course, clothing fits everybody differently, and we all have different preferences, so try on if possible!
Good luck!
