Got both blue and black because I have the original Jon performance pants (the new performance pants are different). If you want the full suit whichi recommend cause the pants are great, be sure to get the latest performance pants with this because the blue is slightly different. I went back and bought pants to match this exactly. The black's match the same tho but I still got the new pants cause they are better design than the previous gen.
The sizing fits good, i just prefer to be more gift-wrapped so i got the sleeves shortened and the back altered an inch tighter- but most probably can wear it off the shelf. Better than all off the rack blazers ive tried, inside pockets are great/practical, material is nice, on the slightly heavier side so it's not a the best for Miami or Dubai summer suit but great nonetheless for the prices
