Apart from the slightly hefty price tag, am super happy w them. These Kyros feel buttery and accentuate my lower body well, like a snuggly hug. Bonus points for being thin enough to be breathable, but still does not show VPL. I feel a lot more confident and comfortable in these compared to cotton ones I was using previously, and intend to use these leggings for reformer pilates, daily WFH wear, or just travel wear.
Based on the size chart, I'm at the upper limit for size S. Indeed, I had to pull them up w some strength when wearing. However once worn they feel perfect.
I tried a pair of Align Lulus in store. Unless you are brand conscious, I'd still say the Kydras are better value; at 2x the price, I don't think Lulu is TWICE as good (maybe 1.25x better?)
