Review on Men'S UPF 50+ Compression Shirts - TSLA 1 Or 3 Pack, Perfect For Athletic Workouts, Water Sports And Rash Guard Protection by Scott Kulothungan

I have purchased four of these shirts. They were all extra large, as previous reviewers said that you should order one size larger than normal. This order seems to be a little larger than the other extra larges.Then I looked through all my old orders and noticed that some of these compression shirts have slightly different numbers and titles, so while they look alike other than color, there are differences.For example:1. Men's Mock Long-Sleeved T-Shirt Cool Dry Compression BaseLayer MUT022. Men's Mock Long-Sleeved T-Shirt Cool Dry Compression BaseLayer Top Athletic (mut 12)3. Men's Mock Long-Sleeved T-Shirt Cool Dry Compression BaseLayer, Zero Block (t12)4. Men's Mock Long-Sleeved T-Shirt Cool Dry Compression BaseLayer, Zero Block (mut32)They are all on the this page in one form or another. The first 3 fit the same despite the entirely different model numbers at the end and slightly different descriptions. The 4th is slightly looser. Now I am confused as to what I will get if I order another one. It is not baggy, and is completely usable, but it is just loose enough to notice the difference.
