Really soft and comfortable for the price!
Special Size: 27.5" Full Length, Size: Small, Color: Ocean Blue, Special Size: 27.5" Full Length, Size: Small, Color: Ocean Blue
These are soooo soft and the quality is amazing! They feel like they would be way more expensive! I love the color and get lots of complements.

Fabulous!
Special Size: 19" Capri with Pockets, Size: X-Small, Color: Flamingo Pink
These are AMAZING! Just received my first two pairs ( black and flamingo pink) and I am back ordering more! They are so smooth and soft and feel great! They fit so well-not to restrictive but have strength enough in the Lycra to look amazing (not the thin, flimsy, cheap tights/leggings). I live in the Sunshine State so I can wear these to workout and run indoor or outdoor practically year round. I prefer this shorter length because they are cooler to wear in the 95° heat 100% humidity. So hoping they make these in the green color and the bright blue color that is available in the full length active leggings! These are my new favorite crop active leggings! Please, please, please make more colors! Amazon, these are fabulous quality and style and at this price point, I'd buy every color and pattern available (I just don't do flesh tones).

Super comfortable fabric and launders well.
Special Size: 19" Capri with Pockets, Size: Large, Color: Taupe
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.
