This is my second purchase of the JINSHI mens underwear. I was a very disappointed as the fit was a bit close, not what I was hoping for. Previously I had purchased the size L US (in 2016), being a 33 waist size which was a bit tight for a while. This time around I decided to go with the XL US, expecting it to be roomier and more comfortable. But this was not the case as the XL was pretty much the same sizing as the L. However, I do like the color patterns, the feel of the material and the nice look.
