I can't fault the product for my bodytype.  I got an XXL but it seemed a little tight.  I returned it no issue though.

I typically wear XL or XLT t-shirts, occasionally need XXL.  The XXXXL perfect even though I have big love handles, it's a road cycling shirt.  I'm 6'6", 270lbs, 48" around the biggest part of my waist (love handles).  The xxxxl is looser and good length for me, but fits well and looks as good as I can look in a cycling jersey.  It covers my backside while riding and doesn't ride up exposing my back.  I bought the Hi-Vis in XXXL, it was tight, the XXXXL is perfect.

For under $10 this is a great deal.  It has good quality fabric, the zipper is not good, but I have not had issues with it.  For a cheap plain jersey, without art, you cannot go wrong.  It is half zip, which I prefer because it looks better than the full zip.  It is not too tight everywhere, compared to jerseys from other discount bike retailers.

I purchased the yellow, white, and black.

Was nervous about the size, but took my actual waist size and overestimated based on other peoples reviews.  I have a 31 in waste and got the XXL and it fits really well.  Great price!

I'm usually an XL, but I decided to order XXL because I've been burned by other online purchases in the past. It fit well enough, but I thought an XXL would have a little more forgiveness. The material is very comfortable and I really didn't want to change out of it.

I bought Large, but when I received it, I realize it comes small and too small. I should've bought XXL. If you are buying this, buy 2 sizes up otherwise it will be too tight.

I am 5'9 and 178lbs. I bought the XXL and it fit great. I have a large bust (36dd) and wide hips so even at this size, it doesn't button but I wouldn't button it anyway. I typically wear a large. The sleeves were the perfect length and so was the waist.

I am 160 and 57. I got a xxl and normally Im a large. I got a top just like this and paid $30. I like this one better. It sits nice on the shoulders and I like the sleeves. Its thick enough to smooth things out:)

I bought the 2XL. I'm a 5'11 215 with wide shoulders, thick chest and a 33 waist.  The 2XL fits comfortably.  It is not tight on me at all.  I like the taper of the shirt.  It goes great with jeans untucked.  The collar is a little larger than I would want but when you have a in-between body like mine you cannot be fussy.  If you have similar dimension you could get away with the XL, if you aren't packing the belly pounds.  There is no give in these shirts.

The material requires ironing.  I am not going to say its cheap, but not exactly comfortable.  I bought this to look good with a pair of nice jeans. I will buy another one, as it is very difficult to finds shirt for my body type.

UPDATE:  So I though I would try the XL for S&G.  Way too tight.  The arms look ridiculous and make the shoulders bunch.  After washing the XXL.  It is just the right size. I will order another XXL.
