These mock turtleneck shirts are great for layering or worn alone. Nice, soft fabric. Colors don't fade. They last forever. I have a bunch of them. I'm a 44 and order up to XL, but the L fits okay too...I just like a looser fit. You can't go wrong with this shirt UNLESS you are one of those guys who thinks a stubby beard is cool...then the top of the mock turtle neck shirt will probably fray, just like all your other shirts.
Bought this for my husband - he loves it. So soft and comfortable. Material is thick enough to keep the chills away, yet smooth enough to be an inner layer. I will probably buy more in different colors.
