Belly Wraps

Belly Wrap Size Calculator

Please note, every “body” is different and determining your postpartum Belly Wrap size is not an exact science. Measure around your belly at the largest part, which is usually around the belly button. In the sizing calculator, select your week of pregnancy and belly measurement. The calculator will generate a recommended size.

How to Wear Your Belly Wrap

The Wrap is 3-5” inches from closing even when you’re stretching it as much as you can – TOO SMALL 🙁
You can exchange it, buy the Extender or wait it out.

The Wrap is almost touching end to end! YAY – this is the perfect fit – just pull it a little and adhere closed, DO NOT EXCHANGE!

The Wrap has plenty of Velcro left - ROOM TO SHRINK! YAY! This is a GREAT fit!

The Wrap closes all the way to the end of the VELCRO – BOO, you will need a smaller size

We recommend sizing for the Mother Tucker Leggings post- pregnancy. However, if you want to have a pair “hospital bag” ready, we’d suggest ordering one size larger than your pre-pregnancy size.

Of course, every “body” is different, so sizing during pregnancy is tricky. While we can’t guarantee 100% accuracy, we can ensure you’ll be getting some Mother Tuckin’ amazing leggings!

Care

MACHINE WASH COLD
Proof undies have strong protection, but should be washed gently. Machine wash in cold water on a delicate cycle, using gentle detergents. To sanitize and refresh, use a few drops of tea tree oil or vinegar in the rinse cycle of your washing machine. Hand washing in cold water works, too!

DO NOT USE
Do not use hot water, harsh detergents, softeners, or bleach when washing as these may compromise the Leak-Loc™ technology.

HANG UNTIL DRY
Once finished washing, hang or lay flat to dry. Depending on absorbency level, Proof’s multilayered technology can take between 6-24 hours to dry. To dry more quickly, blot any excess moisture and hang dry.

To keep you leak-free and worry-free!

Reviews

“So great!! If you’re thinking about getting these just do it! So comfortable and protective. Will be ordering more for sure.”

Amy: Bought Brief

“Now my period underwear are my favorite underwear”

Sierra: Bought Mesh Hipster

“I’ve used other period underwear before and I was shocked at how much better these were — I used to bring 2+ pairs of the other brand just in case. I was more than fine with one pair of Proof® underwear!”
