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.

For their longest life, air drying is best. Hang or lay flat to dry.
Fabric softeners, bleach, ironing, or heat from the dryer.

So comfortable on a plane - wore them on a weekend trip.
Priscilla D. V.Verified BuyerReviewingSuper Leakproof® Cotton Boxer Brief - Rated 5 out of 5 stars2 weeks agoSuper Leakproof® Cotton Boxer Brief
Extremely comfortable and feel confident wearing them.
Lesley O.Verified BuyerReviewingSuper Leakproof® Cotton Boxer Brief - Rated 5 out of 5 stars2 weeks agoGreat feel
Wore it once so far and I love the way it feels but the pad seemed to have moved a bit when I was sleeping and blood soaked the side of the underwear along with the side of the pad.
Kellsey S.Verified BuyerReviewingSuper Leakproof® Cotton Boxer Brief - Rated 5 out of 5 stars4 weeks agoVery comfortable
When I got these, I thought they’d feel bulky, but they don’t at all! Very comfortable and stretchy.
Camila H.Verified BuyerReviewingSuper Leakproof® Cotton Boxer Brief - Rated 5 out of 5 stars1 month agoFirst comfy panty I've been able to wear in a long time.
They are just what I needed especially for sleep. They don't cut into your groin area and move around with your tossing and turning with getting your panties all bunched up! I just wish there were better colors. you can't wear this mulberry or the black under summer whites and pastels. We need beiges.
Merilyn J.Verified BuyerReviewingSuper Leakproof® Cotton Boxer Brief - Rated 5 out of 5 stars1 month agoMy first ever pair of period underwear
And I love them. They're comfortable and the lining is soft. There was one seam in the gusset that I had to lay flat so it wouldn't bother me but that wasn't a problem.
Rachel E.Verified BuyerReviewingSuper Leakproof® Cotton Boxer Brief - Rated 5 out of 5 stars2 months ago5 Stars
These were very comfortable, they had good stretch and didn't chafe or constrict anywhere.
Courtney W.ReviewingSuper Leakproof® Cotton Boxer Brief - Rated 5 out of 5 stars2 months ago5 Stars
I was so pleasantly surprised that this underwear wasn't tight at first. I loved how it fit comfortably right away instead of having to wash and wear a few times before the fabric relaxes. It was perfect from first trying it on.

the elastic edges were comfortable.
ADDIE P.ReviewingSuper Leakproof® Cotton Boxer Brief - Rated 5 out of 5 stars2 months ago5 Stars
Comfortable and much coverage. No dig in and held up well after wash.
LINDA K.ReviewingSuper Leakproof® Cotton Boxer Brief - Rated 4 out of 5 stars2 weeks agoPanty Lines!
I should’ve examined this better in the pictures before ordering, I just didn’t think to. 95% of the time, I wear boxer briefs, so I DONT have panty lines, and thongs can be so uncomfortable and I wear a lot of looser pants, so I can. So obviously that’s what I opted for in the leak proof underwear, but I did not anticipate how extreme the seams are for the absorbent piece are. In terms of panty lines, I may as well be wearing regular, bikini cut underwear, with quite thick seams honestly. I’ll just have to wear them accordingly (around the house etc) and get myself a different cut for everyday use!

I washed them once and everything felt fine, a bit of tightening after throwing them in the dryer but not uncomfortable and they stretched back out after wearing
