Debbra K.Verified BuyerReviewingSuper Leakproof® No-Show Boyshort - Rated 2 out of 5 starsYesterdayI've tried, but these are not leak proof for incontinence
I really wanted these to work, but they just are not leak proof. I love the feel and look, but even with a small amount it leaks straight through my pants or shorts.

Bonita D.Verified BuyerReviewingSuper Leakproof® No-Show Boyshort - Original - Last Call - Rated 5 out of 5 stars2 weeks agoThe go-to OG
I love my Knix. Even after I had my daughter and started worrying about bladder leaks, these have been my go to. They fit perfectly, they’re comfortable, and they’re just like regular underwear. I can wash them like normal, and they dry pretty quickly when I lay them flat. I’ve tried the other cuts like hi-rise or bikini, and nothing really compares to the boyshort in comfort and coverage. I’ll never have to worry when I wear my Knix.

These are very comfortable, don't wedge, and are perfect for not sure if you are starting or are done days.
Lindsay R.Verified BuyerReviewingSuper Leakproof® No-Show Boyshort - Original - Last Call - Rated 4 out of 5 stars3 weeks agoStiff Material
Comfortable and effective for the most part! The only part that was somewhat uncomfortable was the leakproof pad and how stiff/crunchy it feels, even after washing. There are some other brands such as Saalt that have an almost as effective leakproof pad while keeping the comfort
Jessica M.Verified BuyerReviewingSuper Leakproof® No-Show Boyshort - Rated 4 out of 5 stars3 weeks agolove the fit and colour, limited choice
Bought this underwear to match the bra I purchased, I would have much preferred a lighter leakproof version (but only super leak proof was available). The fit and colour are great, but more protection than needed.
Marleen C.Verified BuyerReviewingSuper Leakproof® No-Show Boyshort - Rated 5 out of 5 stars3 weeks agoLove
Restocking some old ones bought a few years ago. Always a reliable and comfortable staple.

Works great for my needs. A little wider gusset would be appreciated to cover all the lady bits.
Terry G.Verified BuyerReviewingSuper Leakproof® No-Show Boyshort - Rated 3 out of 5 stars1 month agoStyle has changed disappointing
i purchase the exact same boyshorts a couple years ago and loved them. the style has changed now and the back seam on the gusset is much higher and shows a seam line on tighter pants. i can also feel the seam and it's uncomfortable. i am debating whether or not to keep these items.
