4 T-shirts - all good

All four T-shirts I bought in S (royal blue, dark blue, red and yellow sunflower), because they would be quite large. The two blue quite liked me, just all have the disadvantage that you sweat pretty much where. This is certainly at the high polyester content (65% polyester 35% cotton) - that's a pity. Since I normally sweat little annoying that and those things need after 1x wear in the wash. Since the royal blue shirt despite min. 15x wash already looks good, I would buy it again.
