Nice but either to loose or too tight in waist

Originally posted on Under Armour

No, I don't recommend this

I wear a medium with their underwear, but the waist was too tight even though the fitment was good in the legs. I had to order the large and they are good in the waist and actually the same in the waist as their medium underwear, but now the leggings are too loose. Especially by the ankles. Will end up riding up. Big bummer.

Appreciate you breaking this down — with the medium waist running tight and the large getting loose at the ankles, that’s a tough fit experience. I’ll reach out by email to help get this sorted.

It's a good fit and comfortable like all UA products. But it is a bit pricey.

Excellent Compression

UA compression pants are the absolute best they fit just right and if you need tall size most times it available I have been wearing UA compression since 2014. The only issues is shipping is slow!

Fits Perfectly.

Fit and length are just what you would expect. I bought these to help keep me cool and protect the back of my knees from chafing from my baseball shin guards.

I never thought I’d wear running tights

Originally posted on Under Armour

Yes, I recommend this

A friend wears these to run and does well (better than I do). I tried these under nylon running pants and the compression makes a huge difference. They fit well and are comfortable.

What I was looking for

Originally posted on Under Armour

Yes, I recommend this

It's a light to midweight layer, perfect to wear under white or light colored trousers. Not for deep cold. Very comfortable, sizing is correct. Elastic band not too tight or loose.

I don't know what kind of witchcraft these are made of, but it works. Not a traditional warm feel, difficult to describe. The important thing is they make you feel warm!

These are great, as a basketball official they keep the right amount of heat in my legs during the games and provide the support needed.
