“Being able to strap this on is my favorite part.” Olivia H.
Why it works
During your period, your uterus squeezes hard to shed its lining. That squeeze cuts off some of its own blood flow, and that's the cramp you feel. Warmth helps the muscle relax and gets blood moving again. Solenne adds a gentle massage on top, like a slow belly rub.
How to use
- Charge it the night before.
- Wrap it around your lower belly or lower back, over a thin layer of clothing.
- Switch it on and pick your heat and massage. Start low and take breaks on higher settings.

Sound familiar?
Day 1 shouldn't cost you a whole day.
The squeeze starts. Then the heavy pressure, like something is pulling down and out. By noon you're curled up in a ball, the heating pad plugged into the wall, canceling plans again.
That pain has a reason: your uterus squeezes so hard it cuts off its own blood flow. Warmth helps it let go. Solenne lets you take that warmth with you.
One belt. Your whole Day 1.

Charge it like your phone.
It holds its charge in your drawer or bag until you need it.

Wrap it on early.
Start the warmth before the squeeze builds.

Keep going.
Work, class, errands, the couch. No cord, no hot water, no outlet.
Same warmth. None of the hassle.
Heat has always helped. Here's what changes when it comes with you.

Real reviews from real Day 1s

I already liked using warmth during my period, so I wasn't looking for some miracle gadget. I just wanted something easier than filling a hot water bottle. Being able to strap this on is my favorite part.

Some days I don't want to explain why I'm quiet or why I need a break. I just want to feel comfortable. I wear this while watching my favorite show and give myself permission to slow down a little.

I'm the girl who packs for every possible situation, especially when my period might show up on a trip. Having this in my bag is reassuring. One less thing to figure out when I'm already uncomfortable.

Questions, answered
Does it really help with cramps?
Heat is one of the most widely used ways to ease period cramps. It helps tight muscles relax and gets blood flowing. Solenne adds a gentle massage on top. It's a comfort tool, not a medical treatment, so if your pain is severe or getting worse, please talk to a doctor.
Is it safe?
There's no boiling water to spill or leak, and you choose the heat level. Wear it over a thin layer of clothing and take breaks, especially on higher settings.
How long does the battery last?
It holds its charge on standby, so it's ready when you need it. How long the heat lasts depends on the level you choose; lower settings last longer.
Will it fit me?
The strap is adjustable. Wear it on your lower belly, or turn it around for your lower back.
Can I wear it at work or school?
Yes. It's cordless, so you can wear it over a thin top, under a loose layer, wherever your day takes you.
I have endometriosis. Can I use it?
Heat isn't right for every condition. If you have endometriosis or another diagnosis, check with your doctor before using heat therapy.
