- Rated 2 out of 5 stars1 month agoDon't stay put
When I tried them on in the store they seemed to fit well but trying to play sports in them they don't stay put. Constantly fidgeting/adjusting them.

Good quality. Haven't usded it yet, so I can not speak about the absorvancy, but it looks pretty well made, and I am happy with this purchase. My daughter is using it for sports and she liked how they felt when she trued them on. Price is high, though, even though I got them on sale, but I think it is worth it. .
IdanaVerified BuyerWas this helpful? - Rated 4 out of 5 stars3 months agoVery comfy but a little big on the waist
I love these, there very breathable and comfy and the color is very pretty. I bought the XL that fits perfectly around my hips and legs with no circulation cutoff but the waist is a tad too loose. It would be awesome if the waist was tighter as I am always pulling them up. For reference I am 47 inch at the hips and 38 inch at the waist which are basically the measurements for an XL so maybe they run a tad too big but the hips and below fit perfectly so I am torn.

Waist band will not stay smooth. Keep folding over
GursharnVerified BuyerWas this helpful? - Rated 3 out of 5 stars6 months agoProduct 3*, customer service 10+*
I was disappointed. There's is very little stretch in the waist line....I couldn't get them on over my hips.
Customer service went above and beyond, to make sure I was happy.

The medium would fit a child
LouiseVerified BuyerWas this helpful? - Rated 4 out of 5 stars8 months agoNice material, tight fit
I like them and will save for period workouts. They definitely made me feel safe that I wouldn’t have leaks! The only downside is they are a little thicker than I like. If you’re looking for tummy control, these are great!
Catherine R.Verified BuyerWas this helpful? - Rated 5 out of 5 stars8 months agoWell Made Shorts
The shorts are comfy and long. The pocket on the side is very well placed and useful to carry your phone. The material is strong. The shorts are well made and keep your thighs from chafing.The leakproof band is useful for leaks!
