Our leggings feature original artwork by our female founder, Chriztina Marie. It all starts with a spark of inspiration and pencil sketch that is scanned into the computer and perfected within photoshop. One design can often take up to 80 hours to complete from start-to-finish: it's all in the details.

Will Not Disappoint

Just beautiful! Like all triathlon leggings from Eagle Rock the colors on these are beautiful, and even more so in real life. I always love feeling my best in the tight compression fabric and am always happy with my purchases from Eagle Rock!

My Go-To Beach Suit

Love all my EagleRock’s Leggings,but these are my Beach favorites! The design just makes me happy — great fit, great style, comfy, and so vogue as to stop folks in their tracks to say how cool they are. Thought the faces on the hips might be too much, but for those asking, NOT AT ALL!! Such Fun…Raven/Moth next on my wish list (gotta birthday coming)! Thanks again for your art and quality workmanship….

If you love mermaids and sirens, you need these

I'm your average, non-patterned yoga/exercise enthusiast but when I saw these leggings, I decided to take the plunge and give them a try. I cannot gush enough about how amazing they look on me and how creamy and gorgeous the colors are. The fabric is fantastic and keeps me hugged in and I love how secure I feel tucking the heel over my feet or keeping them at the ankle. I seriously cannot get enough of them whenever I put these on.

Hey there, Elizabeth! We're so grateful to hear that you're so happy with your Siren leggings! We hope the artwork, colors, and fit make you feel like magic! Enjoy! xoxo, JJ

perfect for any activities!

Pants are great not only for yoga but for running errands too! The fit is so perfect. I suggest to go for a size smaller if you are in between sizes. The tight fit will look so much better.
