Built for an ultra-comfortable fit and feel, while giving you the sweat-wicking, heat-battling, performance benefits you expect from Under Armour, our breathable polos come in all the classic colors.
  • Loose: Fuller cut for complete comfort
  • UPF 30+ protects your skin from the sun's harmful rays
  • 4-way stretch construction moves better in every direction
  • Material wicks sweat & dries really fast

Highly recommended.

It a perfect polo for a very energetic boy. It keeps him cool even if he does a very strenuos activity. Highly recommended.

Excellent Quality

Everything about this garment is perfect and my son loves wearing it for golf. Delivery fast :) Very happy.

It's cheaper to make with seams!

I ordered these same shirts last year for my son's school uniforms. When I reordered this year there is a seam across the upper back of shirt. That was not there before and its very uncomfortable. I won't reorder these shirts again.

Great product

My son is really fussy but won't shop. I bought this and he loved it. Fits great feels really nice and looks fab!

Great Shirt! My son loves it!

This is a great shirt. We bought it for golf, but its perfect for dressy-casual outings as well. He says it's very comfortable and it washes up great. [This review was collected as part of a promotion.]
