Boys' UA Threadborne Polo

Product DNA

This is your new favorite polo—made out of Threadborne Siro so it not only does all the sweat-wicking, quick-drying stuff you expect from your UA gear, but also just feels incredible.
  • Loose: Fuller cut for complete comfort
  • UA Threadborne Siro uses a unique construction to give you greater stretch & recovery, ultra-soft feel & more breathable performance
  • 4-way stretch construction moves better in every direction
  • Material wicks sweat & dries really fast
  • Anti-odor technology prevents the growth of odor-causing microbes
  • 100% Polyester
  • Imported


This is what makes our gear work harder—and smarter—than anything else out there.


The original innovation our founder dreamed up. This super-breathable fabric wicks sweat and regulates body temperature so you feel cooler, drier, and lighter than ever.

Review Summary

Too Small

I have the L (other colors) n my closet and it fits. Ordered this in XL and can't even get it on.

Not what I expected

I had to exchange sizes. I would go up a size when ordering This polo keeps my son cool but it is made of very thin (almost see through) material. He loves it but i would probably not buy this style again.

When will UA learn with its kids polos?

As others have pointed out (with many other shirts, not just this one), the neck hole is too small and difficult/impossible to slide over my son's head. They had this issue with several polos last year, and for some reason have not fixed such a simple problem.

Neck hole too small

Was excited to get this for family pictures but couldn't even get the shirt over my 5 year old sons head. Had to return.

Thin material

Material is thin and the quality of pajamas. I question how will this will stand up to a 12 year boy. Too expensive for the cheap polyester used. Returned.

Neck hole too small

The material is very nice and the colors are great... however I bought this shirt for my 5 year old and the neck hole is just not big enough. Even with all of the buttons open, the material does not stretch at all and he has a hard time putting it on. It's even worse to take off! [This review was collected as part of a promotion.]

Soft material.

Great Shirt for Golf

I purchased this shirt for my 11 year old son. The color is very vibrant and he loves it. Fit seems normal and maybe a little more slim fitting than a few of his other golf polos. [This review was collected as part of a promotion.]
