Our new UnderPatch is designed to help protect your skin from reactions to your device! By serving as a barrier between your skin and device, it helps prevent irritation from harsh adhesives. *Disclaimer: The underpatch is designed for people who have skin sensitivities to the adhesive that comes with their device/pump. Since your device is designed to adhere only to skin, our underpatch should be paired with an overlay patch to ensure your device is secure. Check out our Libre 2 patches here.

Jazz up your device by layering any of our colorful tapes over your device to keep it in place. Included: - UnderPatch Tape - Free Test Patch - Application Tips Is this product right for you?
