Why did you pick this product vs others?: I was looking for a mock turtle neck T-shirt so I was a bit surprised they were almost like a very light undershirt or sweater., or heavy tee. I like to wear them when it's cool or under a shirt or sweater. Washability: Machine wash, dry on warm as it's got spandex in it. Has held up to machine washing without loosing elasticity. Quality: Not a highly refined shirt. Quality is ok but could be better. Weight: About like a heavy tee shirt or very light undershirt. Fit: About like a tee shirt. Loose fit.

The material and tight fitting helps keep you warm…

Size: Large, Color: Green

I am 5’8” tall and weigh in at 172 lbs dressed. These are the most comfortable cold weather shirts I have ever worn. In my humble opinion, what makes these shirts so comfortable and warm is the tight fitting and the soft, fleece like feeling on my skin. I wear and ordered the large size. The shirt is cut so they fit close to one’s body and look great compared to other brands of shirts that end up looking like one is wearing a potato bag. The tight fitting helps keep me feeling warm. No cold air pockets.

Better than expected

Size: X-Large, Color: Light Red

Intended to use it as an everyday shirt but the quality we much better than expected for the price so it's now a more special occasion pullover. Nice soft and comfortable material, well constructed and sewn, good loose but not baggy fit, nice heft and substance around the collar. Lightweight but not thin fabric. Excellent value = 5+ stars
