Nice Quality for the Price
Size: Large, Color: White, Number of Items: 1
I ordered a large and it was a little too big. I washed and dried it and it didn't shrink too much. It's very soft and feels nice. For the price it's better quality than expected. I am planning to order a medium which should be the right size. The large fits my husband perfectly. F/5'11"/165lbs M/6'/170

Soft, Relaxed Fit Tee That Gets Better with Every Wash
Size: Medium, Color: Black, Number of Items: 1
I ordered the Comfort Colors Adult Heavyweight Short Sleeve tee and it honestly lives up to the name. The fabric has that thicker, broken-in feel right out of the package. It is soft without feeling thin or flimsy, and it has that slightly faded, lived-in look that Comfort Colors is known for. The fit is relaxed but not sloppy. It hangs nicely without clinging, and the heavyweight cotton gives it structure. It feels durable and well made, especially around the collar and seams. After washing, it softened even more but didn’t shrink much or lose its shape. What I like most is how versatile it is. It works for casual days, layering, or even as a simple everyday staple. The colors also tend to have that washed, vintage vibe rather than looking overly bright or synthetic. Overall, this is a dependable, comfortable T-shirt that feels like it will last. If you like a slightly heavier cotton with a relaxed fit, this one is a solid choice.

Good basic t-shirt with one caveat
Size: XX-Large, Color: Crunchberry, Number of Items: 1
This shirt has a good weight to it and feels well made. I bought three of them after reading a review at the New York Times. It is a really good t-shirt for a great price. The only caveat is the sizing. For a unisex shirt the shoulder width is a bit too broad for a woman. The shoulder seam is a good two inches below my shoulder. That's probably to be expected, but if you are a woman and that would bother you I would look for another shirt with women's sizing. Also, the neck is weirdly high and I keep pulling it away a bit. Not deal breakers for me but did cause me to knock off a star. If I could I'd give it four and a half stars.

Comfortable, Colorful, Soft, Affordable.
Size: Large, Color: Ice Blue, Number of Items: 1
These T Shirts are as good as it gets especially at the price point. All cotton, very soft, very colorful. Wash well. If you don’t want them to shrink, I suggest air drying them. I had an XL one for years and pretty much ignored it. Found it again and it’s amazing to wear to bed or around the house. At These prices if you need or want a T shirt, this is the one to get.

The Perfect Tee Shirt
Size: X-Large, Color: White, Number of Items: 2
I bought one of these shirts to see if they’re as good as the customer reviews suggest. They most certainly are! They have a nice weight, a great fitting collar, and the shirts have a generous length so they stay tucked in. The sleeves are longer than normal tee shirts, which I really appreciate. These shirts are such high quality, and such an amazing bargain, that I bought four more!
