WHY IT HAPPENS

Why the belly doesn't go back on its own

Pregnancy stretches your belly muscles apart and thins the tissue between them. For many moms, that gap and the stretched skin are what push the belly forward, not fat.

That's why cutting calories often doesn't change it, and why the wrong exercises can make it worse. What helps is support you can wear now, and the right core work over time.

THE MECHANISM

Meet the CoreCross panel

Two firm panels cross over your belly and pull it in from the sides, the way your own core muscles are meant to. Smooth under clothes, soft where you need it.

Stays upGrip waistband that doesn't roll when you bend to pick up a toddler.
Soft over your scarA smooth band sits flat on a c-section scar, no seams pressing in.
BreathesMesh windows so it isn't hot like a faja.
Bathroom-friendlyNo hooks or zips. Pull down like regular underwear.

First tucked-in shirt since my son was born
The c-section shelf was the thing I hid the most. This smooths it out under jeans and the band sits flat on my scar. It does not roll when I sit on the floor with him.

Finally fits a real 2X
Every other brand rolled down by lunch. This stays put while I carry her around all day, and the mesh keeps it from feeling like a sauna.

The box felt like it was made for me
Pretty packaging, and the QR code started the core program the same day. Week 3 now and I actually do the 10 minutes, right next to the baby.

Three babies, one belly that never went back
I tried fajas. Too hot, too many hooks. This is just underwear that holds everything in. I wear it to work and forget it is on.

Questions moms ask

Will it fix my diastasis?

No garment can close a gap on its own, and we won't pretend it does. It supports and smooths your belly while you wear it. The 12-week program is what works on your core itself. If your gap is large or you have pain, see a pelvic floor physio.

How long should I wear it each day?

Start with a few hours and build up to a full day. Take it off to sleep. If you feel heaviness low in your pelvis, pain, or leaking, take it off and check with your doctor or physio.

Can I wear it right after giving birth?

Wait until your doctor or midwife says you're ready, especially after a c-section. It's designed for life after early recovery.

Will it roll down?

The grip waistband and side support keep it in place when you sit, bend, and lift. If it rolls, you likely need a different size, and your free swap covers that.

Is it hot?

Breathable mesh windows keep it lighter than a faja. You can wear it all day in warm weather.

How do I get the core program?

It starts the day your order ships. Week 1 lands in your inbox, and there's a QR code in the box too. Each week takes about 10 minutes a day.

Flat in your clothes today. Stronger core in 12 weeks.

30-day guarantee. Free size swap. Free core program.
