Although they don't feel quite as thick as my 20 year old Beefy-Ts, they are definitely thicker than most of the competing brands. Neck hole is average size, which is ok. So many manufacturers have these enormous neck holes which are uncomfortable when moving and working. The sleeves on the long sleeve Beefy-T are freakin enormous! Length is appropriate but the roominess is ridiculous. One thing I'm unclear on: I ordered 6 Beefy-T shirts. Four are tagless, but two shirts have these annoying 2 inch cloth tags hard sewn into the collar seam. At least Gildan tags are easily removed. These Hanes tags will have to be tediously cut close to the stitching to avoid ripping the seam stitching. Minus one star because of this and the inconsistency of tagless verses tags.
