Review: Awesome - Excellent fit and warmth. Feels soft and comfortable,
Review: Great Shirt - I purchased this shirt because I've had good luck with their products in the past, and the trend continued. Pictures attached for reference. I am 6'1" 185lbs and I purchased a medium. The sizing and fit were as expected. The sleeve length reached my wrists, and the shirt length went about 2 or 3 inches past my belt line. The shirt isn't super tight like a compression shirt, but you aren't swimming in it either. The fabric is VERY soft to the touch, and feels great against the skin. It has some give/stretch to it, but will maintain it's form. The collar fits nice, not too tight against the neck. I found the shirt to be nice and warm, and wear it around the house instead of a light sweatshirt. I'd highly recommend for anyone looking for a long sleeve top.

### ⭐⭐⭐⭐⭐ A great shirt!
*by D***Y on March 14, 2025*

It kept my body warm while I slept outside in 20 degree weather. Of course, I did also have a sweater on, but I survived a really cold night in which my body was covered in frost. So I would definitely consider this a great quality shirt.
