I paid $12.46 for a 2 pack 3XL in blue. 100% Cotton, a bargain for sure by my standards. My intent was to use these as pajama shirts. Very happy with the quality, they are not as light weight as I might have expected. I wouldn't of complained had they been a little thinner cotton, being for sleep ware purposes.
These shirts would make perfectly fine outdoor summer work shirts, in my opinion, YMMV.
As for sizing, I am 6'3" and and around 260 LB. Most of the time I buy 2XL T Shirts because I often find myself swimming in 3XL, the latter are less available and sellers usually price gouge too. Sizing always varies with brands. These Fruit of the loom shirts in 3XL are not overly large, I am not swimming in these. The fit is very good for me. Swimming in these would of been OK for sleep ware. I'm thinking the 2XL might of been a little small on me. These shirts a good quality and a good deal IMO. This is after one wash and wearing.
