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

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.

Great Leggings

These are some of the best leggings I’ve purchased from UA. I haven’t experienced the chafing from other reviews. They fit and look great. I should have purchased another pair.

Too Tight

Well, the material is great. The manufacturing and the tailoring are also great. However, I am skinny, and I wear 30-31 skinny jeans, etc. So I bought Medium size. However, it's very very tight that I couldn't wear them for more than 5 minutes, I felt suffocating. I don't know if they're supposed to be that way. If I want to buy Large, it feels like the large is 3-4 sizes up than my size. I don't know what to do.

First purchase

Great fit, breathes well, not sure if it would stand the UK. Very impressive with the fit and want to just wear that all the time

Size Up!!

I headed some advice from another review and actually bought a size up from the measurements on under armour, but I’m so glad that I did!! This set of gym leggings is such a great fit, and really does give you a performance boost - hands down best gear on the market!!

Très bon produit

Beau produit, belle matière, agréable à porter. Il taille parfaitement bien au corps.

Great looking but uncomfortable

Pros: The leggings fit well and look awesome. I love the cross design. Cons: However, the stitches are on the inside of the leggings, including stitchings of the cross design. When wearing it, the thick stitches get compressed deeply into my legs, making the leggings too uncomfortable for me to wear. Despite of the beautiful design, I will be returning the ones I ordered.

Optik Hui, Verarbeitung Pfui

Das ist nicht meine erste Kompressionshose. Daher ist mir schon bewusst dass diese sehr klein ankommt und man sich "rein pressen" muss. Die Nähte machen aber keinen besonders vertrauenerweckenden Eindruck, der Stoff ist recht dünn. Heißt es macht auch nur Bedingt was er soll. Andere Hersteller sind da effektiver sage ich mal. Der Stoff ist auch nicht wirklich blickdicht. Preis / Leistung stimmt hier nur bedingt. Tolle Optik. Trägt nicht jeder. Vielleicht wegen der Qualität...


Weer een aanrader om aan ieder te kunnen aanbevelen. Aangenaam dragen goede steun waar nodig en mooi.

Powerful leggings

Light, yet strong and traps heat without over overheating. Breathe wonderfully and great cut.
