Review on High Visibility Safety Vest For Men - 12 Color Reflective, XS-8XL Sizes - AYKRM. by Clinton Youmans

I read the reviews about the sizing problem but this was insane. I am an XL shirt size. I wanted to wear this over a winter coat when i walk the dog. My daughter bought me the 3XL as a gift thinking that it runs small. The 3XL ended up being so snug, i could barely close it over my shirt alone without a coat (and i don't have a gut). :-)So we ordered the 6-8XL which turned out to be like wearing a tent. Returned the 6-8XL for the 4-5XL which was a better fit over a winter coat but will be too big to wear over a shirt in the summer.Bottom Line: you'll have to try different sizes to get the right fit.
