    Sweaty Mess

    There is a lot to like about these shorts, but they show sweat stains everywhere other than the liner area, which then also looks kind of strange as a result. Will have to stick to the darkest colours. Sizing is a bit off if you have a smaller waist and strong thighs, but don’t have issues with them rolling up or down.

    Don'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. .

    Very 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.

    Product 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.

    Nice 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!
