What our customers are saying
Customers say these swim shorts are comfortable and provide good coverage, with many praising their flattering fit and confidence-boosting design. Users appreciate the stretchy material and high-rise waistband that stays in place during swimming and active play. Many reviews mention the shorts work effectively for their intended purpose, with several customers purchasing multiple pairs. Common feedback includes concerns about visible lining that can show through like underwear lines, and some note the shorts may ride up on the thighs or roll down at the waist. Several customers mention sizing runs small and recommend ordering a size up. While most find them true to size and well-made, some experience fit issues with too much material in front or legs that are too loose in water.

    I loved these leak proof swim shorts. It gives me a peace of mind not to leak into a hot tub or pool.

    Love!

    I'm an active mom with 5 year old twins and I am obsessed with these shorts! I love that I can run, bend, swim and just generally play with the kids without constantly adjusting my bottoms. Highly recommend! Knix, please make these in more colour-ways!

    I ordered a size small, about 5'5" and 125lbs for reference. They ride up slightly in the thighs on me :)

    Doesn't fit well

    Too much material in the front, too little in the back. Created weird gap in the back under the bum and really tight on the front. Meant that, if I sat down, the legs rode right up like a regular bikini bottom. Returning, unfortunately.

    The effectiveness and ease of use ratings I just put as 3 because I didn't use them but it won't let me submit this review without selecting something.

    So

    I am weeks a way from swimming and have lost some weight about (10 to 12 lbs)I hesitate to order below XL because it could assume too much more movement and the years and weather effect any loss being permanent.

    Cute

    They fit really well. Tight and cute. But the lining underneath shows through so it looks like underwear. Is it worth the price? I don’t think so.

    Not as pictured!

    These are not designed well and look nothing like the pictures. There is a lining that is thick and black with mesh under the shorts, which is very visible. It makes it look like you have underwear on. Does not look good at all! Very disappointed.

    Did not receive

    I did not receive it and I needed it this weekend. I ordered them a while ago to be sure to have them on time, and now I am asked to make a review about something I never received. So here it is : 0 stars.
