I am very picky about the fleece I use for running in cooler weather. I like them really thin so I can layer. This is about as thin as I could find on Amazon but it still has some substance to it. There are several elegant details like the way the zipper tag parks itself in a little pocket. Very nice shirt!

Nice shirt.

Color: Black, Size: XX-Large

Good neck height, not too high, firm neck grip without the choke feel. Clean look when wearing under an open shirt or looks good alone, Soft feel against the skin, and it washes well, no pulling or color fade. semi-form-fitting on the body, but not tight for the size. priced well.

A Difficult to Find T-Shirt

These T-Shirts are nice. A super difficult to find. The manufacturer calls it a mock-turtle neck (MTN). But the collar height is actually a bit shorter than the traditional MTN, which is great. It's closer to a regular T-Shirt that comes all the way to the neckline. And very somt a comfortable. This is the perfect style of T-Shirt to wear under a sportscoat, if desired. Or under a shirt where you want the T-Shirt to show for contrast. Just the right look.
