A closer look
Soft, slim, and made to stay discreet.
The heart-shaped design sits smoothly over underwear and stays low-profile under everyday clothing.
Four simple steps
Open. Peel. Apply. Press.
The pad begins warming when exposed to air. Always apply it to underwear—not directly to skin.
Use with care.
For external use only. Do not apply directly to skin. Check the area regularly and stop use if the pad feels too hot or causes discomfort. Do not use while sleeping. Follow all package directions and warnings.
What’s inside
Familiar materials, thoughtfully layered.
Each pad uses air-activated warming materials sealed inside a soft, wearable design.
Iron powder
Reacts with air to help create steady warmth.
Activated carbon
Helps support the warming blend inside the pad.
Vermiculite
A lightweight mineral used to help hold and distribute the warming materials.
Salt & water
Support the air-activated warming process.
Resin
Helps keep the inner materials contained and evenly blended.
Cotton facing
Creates a soft outer layer designed for comfortable wear against underwear.
Do not cut, puncture, open, ingest, or apply the pad contents directly to skin. Always follow the complete package directions.

Everything you need to know.
How long does the warmth last?
Each pad is designed to provide consistent warmth for up to eight hours. Actual duration can vary with the environment and use.
Where do I place the pad?
Adhere the pad securely to the inside of your underwear over the area where you want warmth. It should attach to the underwear fabric—not directly to your skin.
Can I wear it under clothing?
Yes. The pad is thin and designed to be discreet beneath everyday clothing.
How do I dispose of it?
Allow the used pad to cool completely, then place it in household trash. Do not cut, puncture, or ingest the contents.
When will my order arrive?
Orders are typically processed within 2–3 business days. Standard U.S. delivery generally takes another 3–7 business days after dispatch. Carrier delays and peak periods may affect timing.
