Why Carry On?
It feels like underwear, because it is
Soft, pull-on, cut like your own briefs.
It disappears under everything you wear
Invisible under jeans, leggings, a dress.
Built for real life, not the chemist aisle
Postpartum, perimenopause, the sudden laugh.
Pull on, carry on - no soaking, no laundry
Single-use and disposable. No laundry, ever.
You don't have a problem. The products did.
A leak should never decide your day.
Your body isn't a problem to manage. It's a life to live. So we engineered absorbency into underwear you'd actually choose to wear.

Trial pack feedback
From the people who tested it first.
We sent free trial packs to people living with this, and asked what they actually thought.
I bought these for mum. She's worn them every day for a month and asked for more. That never happens.

First pair I've worn that didn't announce itself. Yoga, school run, a glass of wine, and they just stayed put.
Sarah · 47 · BrisbanePerimenopause · CorePlus
Six weeks postpartum and I wore CoreMax to a wedding. I cried, danced, laughed. Nothing else happened.
Priya · 32 · Sunshine CoastPostpartum · CoreMax
Dad wouldn't wear anything from the chemist. These, he actually puts on. I don't know what you did. Thank you.
Fiona · 52 · PerthCaregiver · Core
Finally something that doesn't feel like thin hospital-grade. Wore them for a weekend walk in the Grampians and forgot they were on.
Mark · 48 · BendigoPost-prostatectomy · CorePlus
Long-haul Sydney to London. Two films, three coffees, no leaks and no worry. That used to be unthinkable.
Tom · 71 · Sunshine CoastTravel · CoreMax
Every quote is from a real tester who was given a free trial pack. Nobody was paid. The 4.9 out of 5 average comes from that same group.
Us vs them.
Not thinner, not louder, not cheaper-feeling. Underwear engineered by someone who needed it, and worn for 400 hours before anyone else tried a pair.

Any last questions?
A pad sits in your regular underwear. Carry On is the underwear. There's no separate liner, no rustle, no movement. The absorbent core is engineered into the pant itself, with fast wicking and standing leak guards to keep you dry.
You can wear any pant all day or overnight. We suggest you change when the pant is either full, at your discretion, or when you feel uncomfortable. For best hygiene, change when used.
Yes. Each product is chlorine free, and we constantly test the pants to make sure we have the most skin-sensitive and odour-controlled products for you.
Women do use these products during their period, though they are designed for bladder leaks, not your cycle, where different odour control and absorbency is required. We do have a dedicated period range in development, expected late 2026.
Posted in a plain unmarked box, wherever you are. Shipping is free for August, and delivery timing is calculated in Shopify checkout.
We have a no-questions-asked 30-day refund policy. As these are hygiene products, you cannot return any used or opened bags; we only accept returns for unopened bags. Contact our support team and we'll sort it.
