I got these because I saw the number of positive reviews and wanted to see if these could be the compression leggings I've been looking for. I think overall they are great, but there are certain details that don't fit what I personally like in leggings, so I will be returning them.
PRO: Fabric is very smooth and the seams don't irritate my sensitive skin. Sometimes the super smooth leggings can irritate my skin, but these don't. Pockets are not bulky at all, you don't even know they are there until you use them and they do not take away from the silhouette. Even though I'm of average height (5'4") they were not too long, which I appreciate. I like the compression, it's not so compressed that it's uncomfortable that you can't wait to get out of them.
CONS: Based on the sizing chart I am XS. I have the same measurements as the model in the photo. (5'4", Waist 25", 34B) and while they fit correctly, you can see from my photo that it pinches at the waist and the skin bulges a little bit. Mind you, this is after finishing the 21 Tone Challenge so my waist is feeling pretty snatched right now. Also, I find that the waistline is so sinched that it was a bit of a struggle to get it over my butt. I didn't struggle to get my legs in, which is nice, and something I don't like about a lot of compression leggings. I understand that this probably helps the leggings from falling, I just don't like that feeling like my waist is being pinched by a rubber band. I'm sure if I lose a little more weight I wouldn't have much of an issue, but I just prefer the waistline area to be flat. Lastly, they do show cameltoe, but it's not super obvious.
Note: The drawstring doesn't do anything for me as I don't normally have issues with leggings slipping. Also because these sinch so much on my waist the drawstring is just there for looks. It would make more sense if the drawstring could actually loosen/tighten the top of the waist where it sinches.
Overall: If you are looking for compression leggings with added pocket utility, these are awesome and very comfortable. Depending on your body shape you might find some difficulty getting into them and getting them over your booty/hips. For smaller sizes, the drawstring seems to be purely for aesthetics.
