Super soft fabric with a nice high waist that does not seem to rolll down when exercising, Yeah! As always I love a good cell phone pocke. After the comfortable fit I also ordered the Slate Blue version. BTW, I have had 2 knee replacements so this below the knee length is a perfect solution for my vanity issues!.

Great product and quality!

Special Size: 19" Capri with Pockets, Size: Medium, Color: Slate Grey

I got the matching sports bra for these and I love the set together and honestly really liked the shorter leggings. The quality is incredible and super comfortable. For the amount I spent on this set it was absolutely worth it. The material is definitely thick enough so they are squat proof but they fit a little loose. I think I would size down one size if I bought another color in these. Overall great product!

THESE

Special Size: 19" Capri without Pockets, Size: X-Small, Color: Navy

I love these leggings! Purchased Navy seriously I have had a gazillion brands, styles types, ie. flare, etc. over my legging years of which there are many. These are the best so far. Perfect for ME. I am 112lbs. 5'1" so not 'normal human size' as my kids say. The small is perfect. Hits 'capri' length on my smaller frame a little longer for me so yay for that too. These are super good quality and I am picky about leggings. They are better than Costco WHAT? Yes they are. **NOTE: These do NOT have a phone pocket which I was also looking for. I am over phone pockets for now. These you could dress up for a night out. Buying every color. The price point is low-so were my expectations. But VOILA! These were a super surprise. Happiness is my Amazon delivery human.
