How to Protect a FreeStyle Libre 3 & Libre 3 Plus Sensor

The compact size of FreeStyle Libre 3 and Libre 3 Plus makes these sensors convenient to wear, but everyday activity can still expose a CGM to clothing snags, bumps and situations where additional adhesive reinforcement is useful.

There are several ways to add protection without treating every situation the same.

Libre 3 and Libre 3 Plus overpatches

Adhesive overpatches provide additional adhesive coverage around a compatible sensor. They are a straightforward option when reinforcing the sensor area is the primary goal.

Libre sensor covers and guards

A compatible cover or guard adds a physical layer around the sensor. This approach focuses on shielding the sensor area from everyday contact and snags rather than simply adding more adhesive.

Reusable Freedom Band protection

A reusable armband provides another option for people who want additional physical security. Our Freedom Band system works with compatible protective cases and is designed to be removed and reused.

Libre underpatches

Skin barrier underpatches sit beneath a compatible sensor rather than over it. They can be considered by customers who prefer an additional layer between the sensor adhesive and their skin.

Can Libre protection products be combined?

Compatible accessories can often be combined when they are specifically designed as a system. For example, a cover may be paired with an overpatch or compatible reusable band. Check the instructions for each accessory before combining products.
