Can someone tell me what brand of clothing this is? (Sports/Yoga gear)?

It has been driving me insane for quite some time. I watch and follow Zuzana's exercises, and I absolutely ADORE her clothing. The only hint I have is the brand logo (somewhat easy to see in the pic given by the url below) I know this is for exercising/yoga clothing. To describe the emblem in words it looks like a solid white circle (filled white) with a horseshoe (almost celtic like) in the center. Please if anyone knows this brand I will be so happy and grateful! Not only are the outfits very pretty, they seem way more durable and long-lasting than what I typically find.
