Product DNA

“Project Rock is not a brand, it’s a movement. It’s a core belief, that I 100% don’t care what colour you are, how old you are, where you come from or what you do for a living. The only thing I care about is you and me, building the belief that regardless of the odds, we can overcome and achieve—but it all starts with the work that we’re willing to put in with our two hands."—Dwayne Johnson

Too Tight

I am 5'9" and 172. These pants look great but the fit is odd. When I initially put them on, I thought I had either bought the wrong size or wrong GENDER. But no, it was a men's medium as I ordered. I've never had sizing problems with underarmour before. I worked out in these and felt smothered and like it was too much pressure on my legs. These hindered my performance if anything.

Great full length leggings

These are some awesome leggings they have the Rock logo on the back leg. Love the color and they have really good support I am really really impressed with these. You can't go wrong with these.

Great Look!

He just loves these!! Very comfortable, true to size and the look is awesome. Definitely a great purchase.


I love these leggings so much I bought two. They feel great, fit great, and look great.

Love them

I love all under armour products if I had more money I would buy alot more

Great leggings

Great! Fit as expected. A side pocket would be nice. If they came in more colors, I’d get a few more.

Works Like a Charm

I've been a huge fan of the rock promoted gear. They work well, look super nice, and are durable. These leggings are very comfortable and I wish I'd bought them sooner. Not too tight, no pinching or bunching, and they feel muuuuuch better than some of my other cheaper leggings. Definitely recommend!

Good compression and fit.

While this isn’t a hog compression legging. It’s a good comfortable compressive base. No pinching or binding in the crotch, good fit.

Love these!

I love these leggings. They look great and feel great. With all the different material, they do feel a little strange but you’ll get used to it.

More supportive than regular leggings

Compared to the threadborne leggings I have in the same size , these feel more supportive and tighter. No discomfort from the Xband though they do leave marks but I expect it from compression gear. They work great for me for sensory awareness.
