Most heat stops working the moment your day starts. The pad needs a wall. The hot water bottle is cold in 20 minutes. The patch is in the trash by dinner.
Purly stays on for up to 8 hours, cordless, under your clothes. And because day 1 doesn't hurt like day 3, you get 25 heat + massage combos to match the day you're having.
If heat has ever helped your cramps, Purly is built to keep it going. In a 2001 clinical trial, continuous heat worked as well as ibuprofen (Akin et al.). Many customers with endo, PCOS or fibroids use it on their worst days.
One honest note: if cold helps you more than heat, Purly isn't for you. It's a comfort device, not a medicine.
You'll feel the warmth within seconds of turning it on. Most customers keep it on for the whole morning of day 1, or through the hour while their painkiller kicks in.
Yes. It lies flat under a sweater, a hoodie or scrubs. Turn the massage off and it's completely silent, so nobody in the meeting or the classroom knows.
Step 1: Strap it around your lower belly or lower back, over a thin layer of clothing.
Step 2: Pick your heat (5 levels, up to 140°F) and massage (5 modes). Start on level 2. Go up only if you need it.
Step 3: Go about your day. No cord, no outlet.
- 5 heat levels, up to 140°F (60°C)
- 5 massage modes, with or without heat
- Up to 8 hours per charge, depending on settings
- USB-C charging
- One zone at a time: belly or lower back
In the box: Purly belt, USB-C cable, Cycle Comfort Guide.
The massage is a gentle vibration, not a deep-tissue massage. Turn it off and Purly is completely silent.
Try Purly through 3 full cycles. If your period days aren't easier, contact us within 100 days and we'll refund you in full. No questions asked.

Day 1. Still at work.
Where Purly goes on the days that used to send them home.
Wore it to work under my cardigan. Nobody had a clue, and I didn't go home early.

Finals week landed on day 1. Heat on, notes out. First exam I didn't spend doubled over.

I take my Advil and put this on before my train. By the time the pill kicks in, I'm at work.

My plug-in pad kept me on the couch for 3 days. Now I can actually get up and move.

I'm a server, on my feet for 10 hours. Cramps used to send me home. Now I wear this on low under my apron and keep going.

Wish I'd bought it sooner
I've had brutal periods since I was 14 and thought this was just another gadget. Two cycles in, I don't reach for the heating pad on the wall anymore.

Most belts only get “warm.” This one actually gets hot on level 5. Not a cure, but I can sit at my desk again.

She used to cancel plans on day 1. She wore it under her dress to my sister's wedding and stayed till the end.

Better than waiting it out
Advil + Purly is my day 1 routine now. The hour before the pill works is so much easier.

3 cycles later, here's what changed
We asked 500 Purly customers what day 1 looks like after three cycles with the belt.
Fewer days cut short. Fewer heating pads tied to the wall. More meetings, shifts and classes finished.
Built for your worst day. And your easy ones.
Up to 140°F on level 5. Hot enough for the day the cramps come in waves. Steady for hours, not 20 minutes.
Day 1: high heat + massage. Day 3: low, silent heat. 5 heat levels × 5 modes = 25 combos, so you're never stuck with one setting.
Up to 8 hours per charge, USB-C. Your desk, your shift, your train. Not the couch.
Lies flat under a sweater, scrubs or a hoodie. Heat-only mode makes no sound.

Does Purly help with endometriosis or PCOS?
Many women with endo, PCOS or fibroids use Purly on their worst days, often on the higher heat levels. It's a comfort device, not a treatment, so keep your doctor in the loop.
How quickly does it heat up?
Within seconds. Turn it on, pick your level and feel the warmth almost right away.
Can I wear it at work or under my scrubs?
Yes. It's slim and sits flat under loose clothes. Heat-only mode is silent, so it's meeting-friendly.
Is the massage loud?
It's a gentle vibration. Turn it off and Purly is completely silent, which is how most people wear it at work.
Can I use it with ibuprofen?
Yes. Many customers wear Purly while they wait for their painkiller to kick in.
How is Purly different from a hot water bottle?
A hot water bottle cools down in about 20 minutes and keeps you on the couch. Purly stays hot for hours and goes where you go:
- 5 heat levels
- 5 massage modes
- Cordless and rechargeable
Will it fit me?
Yes. The soft, adjustable elastic strap fits most body shapes and sizes.
What's included?
- Purly Cramp Melt Belt
- USB-C charging cable
- Cycle Comfort Guide
How long does the battery last?
Up to 8 hours per charge, depending on your heat and massage settings.
Who is Purly not for?
If cold helps your cramps more than heat, or your pain is new or severe, talk to your doctor first.
What's your return policy?
Try it for 100 days. If it doesn't make your period days easier, we'll refund you in full.
How long does delivery take?
Orders ship within 1–2 business days, with free US shipping.
