Its well made despite what other ppl have said in their reviews. Looks like QC caught up to the returns. There is a problem with the sizing chart. If you look at the collar circumference for the XS size, you will see that the given number is 20.5. Am usually a large and my neck circumference is about 15.5 to 16, I am six foot and 200 lbs.  I like going a bit larger, more like 16.5. There are similar problems with the other numbers like chest sizing. I measured myself with a tape at 42 for a large which is my normal size but their chart says a large is 24. If you assume that they are only using half the circumference and you double it, that is still 48 and that is wrong. Am pretty sure they aren't talking metric sizing here.
If you look at the reviews you will see that abt 68% say that this fits about right and thats fine if you just got out of a Vietnamese pow camp after 12 years in solitary confinement.
Look at the cut...it is narrow at the waist and shoulders. Its gonna be a snug fit. If your weight doesn't fluctuate much, you have a 50/50 chance it will fit ok. I am not into the new skinny look...none of that stuff looks like it fits properly BUT I think one reason this is cut the way it is is because some ppl might want to wear other gear on top of it such as utility belts and so on. This is also the reason the pockets are cut the way they are, high.
Jacket is well made, no defects. I sent mine back for an xxl size. Well see how that fits...does have a weird double pull zipper that is totally useless. That can be annoying. Lotsa pockets and nice Velcro panels. Dont plan on conceal carry as I think the cut doesnt lend itself to that.
