Nice material, holds collar shape well.
Color: Wine Red, Navy Blue, Black, Size: Medium
Good value for the money. You can machine wash and dry on low heat, in my opinion. Laying flat is too much of a pain.

Not made from the most comfortable fabric
Color: White, Light Gray, Black, Size: Large
It is not the most comfortable fabric which makes it not suitable for summer clothing. Also, the fitting of the neck doesn’t look good since material is not wrinkle free

Excellent Mock Neck T-Shirts
Color: Wine Red, Navy Blue, Black, Size: Medium
As a man who appreciates comfort and style, I can confidently say these August Alley mock neck t-shirts are a solid choice. I'm always looking for versatile basics, and these fit the bill perfectly.
The cotton material feels great against the skin, and they've held their shape well after a few washes. I appreciate the slim fit; it looks modern without being too tight. Whether I'm wearing them casually or layering them under a jacket, they always look sharp.
For the price, getting a 3-pack of these quality shirts is a fantastic deal. Highly recommend them for any guy looking to upgrade his basic tee collection.
