Underwear for
Pelvic pain.
Warmth and TENS where you need them, front and back, in underwear made to be wanted, not just worn.
All the care, none of the pain points.
Cinder brings two trusted, drug-free technologies, gentle heat and TENS, to the exact places pelvic pain lives. It's built into soft, beautiful underwear you'd wear for its own sake, and controlled from your phone, so you can get on with your day while it works quietly in the background.
THE TECHNOLOGY INSIDE
Warmth & TENS, exactly where it hurts.
A dual membrane sends soothing heat and TENS to two zones at once, your abdomen and lower back, the places pelvic pain tends to settle.
-
Ultra-thin membranes that feel like fabric
-
Heat + TENS activated independently in 6 different zones
-
Battery designed for a real day's use
The underwear itself
Beautiful first, technical second.
Seamless, second-skin pieces designed to be wanted for their own sake, soft on the skin and elegant enough to choose on looks alone. The technology tucks invisibly inside, held exactly where it belongs.
-
Soft, seamless and made to feel beautiful on
-
Designed to be chosen on looks alone
-
Shaped by two decades of intimate-apparel expertise
The app in your hand
Comfort that adapts to your day.
Direct warmth and TENS to the zone that needs it and adjust the intensity in seconds. Cinder learns your patterns and hands you the control, morning, night, mid-commute.
-
Target the exact zone that hurts
-
Dial intensity up or down anywhere
-
Tunes to your patterns over time

Please talk to your doctor before use if you're pregnant, have a pacemaker or another implanted device, a heart condition, or epilepsy. Cinder is designed to support pain management and is not a substitute for professional medical advice, diagnosis or treatment.
It made it super easy to address my pain in a customizable, modular way.
