Mediocre mens shirt
Material feels great, however the product doesn’t hold up to laundry when following the instructions. The process makes it acceptable, you can get maybe 6 wears out of it before it makes a great Buffy cloth for waxing car

Good quality! Very fair price.
Color: White, Size: X-Large
Great quality!!! Good pricing as well. Normally buy LL Bean, these are half the price and will likely not shrink!!! Typically wear them under another sweater or shirt. Size fit good with exception of sleeves' which are at least 2 inches longer then most of my XL shirts...just rolled them over!!! Good look for sure!
