What size would I get if I have a slim build? 6 foot tall, ~160 lbs

Well I just got my jacket and it fitx perfect!! Im 5'8. 35 waist with a 43 chest. Large fits perfect. I have longer arms than the normal male. I can fit a nice heavy or regular hooded sweater underneat. Now if you live in a hot climate place, i recommend buying a medium jacket. Matter of fact the jacket i bought is perfect for the high altitude of Bogota Colombia. Just to mske sure my message to you is clear, next year i will buy the unlined western jacket a size medium and i bet dollor to donuts it also will fit perfect. Bogota gets cold and hot within hours so i need both sizes. This perfect macho jacket is just like the pants so that means double ply jeans. I tell you you will fry in this great auality jacket that was made to last for twenty years. Hey, honestly, if you have the money buy both sizes at the same time and be happy. I would if i was livjng in theUSA still making boogle bucks. Lol. Lol. I purchased moss color anc im so happy. My next color will be black. I dont by blue because it makes us men look like we are in a time warp meaning the 70's again. Lol. Great, great, great buy wow!

Whats the difference between a xl and a xl tall? my boyfriend is 6'2 and about 200 pounds maybe 190. if he likes a roomier fit what size should i get.

I am 6’2” and weigh 225. Buy the regular XL. The sleeves are plenty long as is the body. I pondered the same question as I frequently buy Tall sizes, but in this case it is not necessary.

I'm 5'8 290 pounds, usually wear a 2xl, but don't want it to be too tight or too baggy. Should I get 2x or 3x?

I'd go a size larger, then. May shrink in wash/dry.

the title shows denim jacket，but detail shows 100% cotton. I really want to know how it feels like ? Rough or soft

It is 100% cotton. It is pretty soft for a unlined jacket. It is heavier then I expected, which for me is a plus. However it is not as heavy as a Carhartt jacket. I think this jacket is by far the best denim jacket I personally have owned. I hope this helps.
