High quality, super soft, good neck height, nice price, ready to go right out of the dryer, medium thick material, works well under a sport coat or sweat shirt, snug fit--runs about one size small. Length is about four inches too long. So, ideally made for tall and skinny people (I am short and thick), but going one size up works fine for me except have to tuck it in due to the length.

This shirt is a cheat code

Color: Black, White, Navy Blue, Light Gray, Size: XX-Large

These shirt fits my body so perfectly! I’m 6’5” 310 pounds but I look 260 pounds. I sweat easily and I’m very sensitive to the material a piece of clothing is made of. This shirt is lightweight, extremely breathable, and feels like silk on the skin. It compliments and accentuates my contours to enhance my physique. I only tried on one and I’ve already ordered 12 more hehe. This is a cheat code.
