Good looks but cheap fabric
Size: Large, Color: Light Blue
The sizing is about right, but the fabric is really cheap, flimsy and rough. Disappointed and this is going back

Nice!
Size: Medium, Color: Bright Blue
My husband loves these. He’s got black, navy, bright blue, burgundy, grey…. and I’m sure I may be missing some! They hold up nicely after repeated washings in cold water in the machine and I always hang to dry. For golf they are fabulous because they are non constricting and comfortable while playing in the hot Florida sun which he does on a daily basis. They run very true to size….he takes his usual medium and they fit perfectly. Highly recommend!

nice fit
I am thoroughly impressed with this Amazon Essentials white shirt. For the price, the quality is outstanding. The fabric feels soft, breathable, and has a good weight to it

Nice shirt, great price.
Fit Type: Regular Fit, Color: White, Size: Medium
Worn it twice and I find it very comfortable. I wear it outside and casually to protect my arms and neck from the sun and find it more comfortable than a long sleeve t-shirt. The price is comparable. If I was to wear it to the office it would have to be ironed. I bought one shirt to try it and I will be buying more.

Nice shirt!
Fit Type: Regular Fit, Color: White, Size: X-Large
I added one of these shirts to another order just to see if they were any good. I was pleasantly surprised by the quality. It fits perfectly and looks pretty nice for a low cost casual dress shirt. Materials seem decent quality. Comfortable, soft fabric. Didn’t shrink too much in the washer and dryer. We’ll see how it holds up long term but so far so good
