Good cotton shirt
Size: Large, Color: Blue/White Palm
Nice shirt for low price AND 100% cotton! Prepare for shrinkage with warm water wash and medium heat dryer. Use cold water and hang dry to keep length

Decent polo
Size: X-Large, Color: Red
Decent quality, I ordered XL which fit loose until I washed/dried it now it fits pretty good. I will say the neck hole is rather large compared to my more expensive polos

Perfect Red for Pentecost!
Size: Large, Color: Brick Red
This polo is the perfect fit for my athletic, 67 year old husband. We wanted to wear red to Church for Pentecost, and this scarlet red matched my dress, perfectly!

Could be 5 but it’s 3 stars
Size: Small, Color: Bright Emerald Green
These polos considering the price and more than decent quality in general, are easy 5 stars plus… however quality control needs to step it up.. these shirts are hits and misses and you never know what your going to get. This green polo was a miss. The left shoulder has an overlap on the seam at the should and sleeve of which creates a horn like effect when wearing the shirt. Looks like the outfits worn by villains in the power rangers series. But like I said, can easily be 5+ stars and even on this defective shirt, the material is very good for the price. I recommend these polos but just expect a few will defective.
