Size and Fit Guide
How to Measure
In order to select the correct sizing, we recommend you take the following measurements using a soft tape measure. If necessary, ask someone else to help.
Waist
Measure around the narrowest part of your torso, usually just above your belly button. Keep the tape snug and level, but not tight. The number where it meets is your waist measurement.
Hip
Stand with your feet together and measure around the fullest part of your hips and buttocks. Keep the tape level and snug, but not tight. The number where it meets is your hip measurement.

- Rated 5 out of 5 stars3 minutes agoPerfect
I love that the lines are pretty seamless and the closest to truly no show that I’ve found truly.
ASAmanda S.Verified BuyerReviewingSuperPlus Leakproof® No-Show Bikini - Rated 5 out of 5 stars4 days agoVery comfortable
I wss able to wear all day without any leaks.
RHRobin H.Verified BuyerReviewingSuperPlus Leakproof® No-Show Bikini - Rated 5 out of 5 stars1 week agoConfortable and reliable!
Hands down the most comfortable underwear I have ever owned. The fabric is incredibly soft, flexible and breathable. The design molds perfectly to the body without any bunching, providing completely reliable, leakproof protection that gave me total peace of mind. I absolutely love the quality and fit of the design and highly recommend it!
AWAmy W.Verified BuyerReviewingSuperPlus Leakproof® No-Show Bikini - Rated 5 out of 5 stars1 week agoFit wonderfully,great leak proof design
These are very comfortable and fit great plus they are super leak proof. so far not a single leak in them.I am very happy with these undies.
SGStephanie G.Verified BuyerReviewingSuperPlus Leakproof® No-Show Bikini - Rated 5 out of 5 stars1 week ago5 Stars
the only underwear I wear. I'm older now & having had 5 children, my pelvic wall isn't the strongest. I'm menopausal & I love these underwear so much, I've bought them for my older sisters & they agree that they are the best.
AAlbertaReviewingSuperPlus Leakproof® No-Show Bikini - Rated 5 out of 5 stars2 weeks agoBikini style
Didnt need the new super protection style? But they are smooth and comfortable in spite of the b additional coverage l
JMJoyce M.Verified BuyerReviewingSuperPlus Leakproof® No-Show Bikini - Rated 4 out of 5 stars2 weeks agoI wish I had found these sooner
I love these underwear. The biggest benefit for me is that the lining goes all the way up. I wish there were more colour options with this feature.
My only complaint is that my first pairs are not holding up. I’m not sure if I was washing them incorrectly, but the stitching is coming undone on a couple pairs. Also, the lining is disintegrating on some pairs. I’m still giving a 4 star review because I still love them despite the issues, and because I’m not entirely sure I’m not to blame for not rinsing them sooner or washing them incorrectly.
JCJennifer C.Verified BuyerReviewingSuperPlus Leakproof® No-Show Bikini - Rated 5 out of 5 stars3 weeks agoGreat post partum undies!
I am such a huge fan of these super plus leakproof underwear from Knox - they’ve given me such confidence in doing activities where incontinence might be a concern 16 months post partum. Cannot recommend them enough!
HMHilary M.Verified BuyerReviewingSuperPlus Leakproof® No-Show Bikini - Rated 3 out of 5 stars3 weeks agoLeaked right through the middle
I wore it for the first time ever for bed and when I woke up in the morning, it leaked straight through the middle and went all over my pants. Maybe it’s better just to wear it during the day.
ELEva L.Verified ReviewerReviewingSuperPlus Leakproof® No-Show Bikini - Rated 3 out of 5 stars4 weeks agoThey make me sweat!
I was excited to try this style because if I leak, it tends to be at night, towards the back so the extended liner sounded ideal, but omg these make me so sweaty! It could be 50 degrees in my house and my buns would still be sweating in these. Honestly, I just can’t wear them, I’ll stick to the ones with the normal sized gusset and wear a pad as a backup.
LGLeAnn G.Verified ReviewerReviewingSuperPlus Leakproof® No-Show Bikini - Rated 5 out of 5 stars1 month agoGreat!
