Comfort and Performance
These Run Tights are great running tights. I enjoy the comfort and performance of the “fit to skin” feel. I have used them at 25 degrees (doesn’t get much colder in Albuquerque), and am happy with the warmth of the material. The reaction energy I get while working out has enhanced my training.

Great Product!
I love these things!

I have typically worked out in shorts, but I saw these tights at a UA outlet store for half off, so I thought I’d try them. It was money well spent. The material wicks away moisture, which can create friction on runs. The material prevents your sweaty legs from rubbing together. They look real good too. And comfort? I see why I see a lot of women wear leggings. I’ve asked for another pair for Christmas.

Great job, UA!

The tights work great
These tights fit great. They sit lower on the waist than other Under Armour tights but stay in place even without a drawstring. The speed pocket holding a phone seems to help with that. I was worried about the speed pocket holding my phone, but I have a smaller phone so no issues with it falling out. They kept me warm in mid-20 degree weather.

Nice but...
The legging did what I expected. Good fit, good comfort, excellent at keeping my legs warm. What I didn't expect was the seam to come undone in the crotch after one wash. Now I have a small that is only going to get bigger. Customer service did an admirable job of assisting me to replace the item. I was hoping to use these during my upcoming Ragnar Relay but the replacement will be too late. I know that Under Armor produces many pieces of clothing so some flaws get through Q&A, this was just disappointing.

No issues with product
I ran at 34 degrees Fahrenheit with no issues. I was not cold and the material maintained my body heat. I ran for one hour with the temperature remaining at 34 F. I wore the cold gear CGI infrared Balaclava as well. As for no draw string on previous comment, there was no issue.

No internal drawcord
As another reviewer eluded too, fabric is lightweight and may not be warm or durable. My biggest objection with these tights is no internal drawcord. Would never purchase a pair of tight/shorts without one, and in particular with a speed pocket where you might need additional support. Will be returning.

Keeps you warm without over heating
Bought a pair of these leggings to try out and I was not disappointed. These leggings fit very well and are extremely comfortable. I have used them to run in temperatures ranging from -5 to -25 and they kept me warm without over heating. Love them so much i just bought another pair.

The only suggestion I have is with phones growing in size these days the phone pocket could be a bit bigger or stretch a bit more so bigger phones can fit in it.

Great Fit
Running tights fit great. Can’t believe how well they fit and stay in place while doing my basic 5 mile run. The only issue I have with this pair, as with most others I have, is that they are so high-waisted. When wearing properly with the drawstring tied, they are for me, uncomfortable. Therefore, I roll the waist down to a more comfortable position. But that also makes the great pocket unusable. All this is basically my preference though and really does not reflect UA running gear. These performed as expected and better.

Best running tights ever
Best men's running tights ever, very light and comfortable, like the second skin. Would be even better if UA will make them with ankle zippers
