Excellent value and has saved me from the sun!
Fit Type: Regular Fit, Color: White, Size: Large
I ordered this large mans shirt because it was 100% cotton and long sleeve. I am a woman and use it to protect myself from the sun walking my dog, very stiff at first, but comes out with several washes. I love the shirt!

NICE Shirt that SHRINKS!!
Fit Type: Regular Fit, Color: Blue, Size: X-Large
Loved this shirt right out of the package. Put a little steam pressing on it and it was perfect. Has a thicker softer feel than most casual dress shirts. Ordered XL with the "regular" fit and it could be worn tucked or out without it looking overly blousy. SADLY, after a first wash on cold and tumble dry low, and pulled it out early and it shrunk by almost a full size!!! The sleeves, length of shirt and overall fittage shrunk so that now it fits like a snug large. I've never had a shirt shrink like this, hence, the one star off. I would have given it 2 stars off, but the original quality of the shirt is nice, just beware of the shrinkage factor. Don't put it in the dryer at all, only air dry it. I'm tempted to reorder another but just then never put it in the dryer.

Shirt worth buying several times
Size: XX-Large, Color: Anthracite Polo Stripe
Purchased another of same order and have found them to be excellent. Comfort, sizing, and quality. Can be dressed up or dressed down and they look great either way.
Worn in very hot weather and have not been oppressed by sweat. Nice. Will be purchasing more. Sizing was great. Loose and long enough to land just right over pants pocket top.

Great Quality and Comfortable Fit
Size: Large, Color: Washed Blue
I picked up the Amazon Essentials Men’s Golf Polo Shirt, and I’m really impressed. The fabric is soft, breathable, and lightweight — perfect for hot days on the golf course or casual wear.
The fit is spot-on, not too tight or too loose, and it looks sharp tucked in or out. It’s held up well after multiple washes without shrinking or losing shape. For the price, it’s excellent quality and a great value.
If you need a reliable, comfortable polo for sports or everyday wear, this one is a solid choice. Highly recommend!
