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!

(Not so) fun fact:

Postpartum bleeding and discharge can last up to 6 weeks.

Fun fact:

Proof-partum panties can hold up to 4 regular tampons worth of blood.

Changing pads just got well…a lot less necessary. Proof® undies are truly panties with a purpose.

These ultra-absorbent, leakproof underwear are designed with our patented Leak-Loc™ technology. This innovative moisture-wicking system prevents vaginal bleeding and discharge from escaping the underwear. The best part, is they look like “real” undies but act like an absorbent pad. Finally, postpartum protection that makes you feel comfortable and confident. Lose the pads, get the Proof!

*STANDARD 100 by OEKO-TEX® certified + Free of PFOA/PFOS, lead, phthalates, and other harmful chemicals, and are Prop 65 compliant.

Proof® is the premiere FDA Registered Medical Device brand in Maternity and Postpartum Support Products.

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.

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!”

Adrianne: Bought The Hipster

So Worth it!

I was a little hesitant about getting these since my flow on my heavy days is a lot. I got these to see how they could hold up with my heavy day. To my surprise, they were amazing! They held up really well. No leaks, smells, and best of all, they were super comfortable! I hate pads and really dislike tampons, so being comfy and good for the environment, as far as reducing waste, is always a big plus for me!! Will definitely be getting more in different styles.

So far so good

I purchased these for after baby… And there on after as well. I’m glad I looked at sizing as they definitely run big! In leggings I’m normally a small with belly bandit but after seeing that these run large I ordered the extra small. So glad I did! They fit well, are not tight but the small would’ve definitely been too big! They seem very well-made and I am excited to use these towards the end of my postpartum. As opposed to pads the entire time.

Welcome to Bandita Club — all bellies welcome.
