Great vest but man are these big and tall. I usually wear a 3XLT so I got a 2XLT so it would be a little snug and I honestly could have gone with a XL for a better fit. There is a ton of room in these I'm 6'5" and 290lbs and there is plenty of space even with layers underneath and the material goes past my thighs probably the longest shirt/jacket I've ever worn.THERE IS NO QUESTION IN MY MIND BUY BRAND NAME PRODUCTS.Perfect and extremely light weight. I'm 6'5" 295 and the XLTall fits me well. It is slightly longer than I expected when standing up, but perfect when bending over or sitting down. I suspect that these run large.I'm a big guy that has a hard time finding clothes that fit. This vest is cut and sized perfectly for someone that wears a 4XNo, is too long. I have to use for a presentReally, really long.good.
