3NOT JUST A PATCH
Not Just A Patch Freestyle Libre 2 Covers (20 Pack) - Thin, Strong and Light, Ultra-Long 14 Day Adhesion - Durable Lingo CGM & Libre 2 Sensor & Protector Patches - Air Libre 2 Beige
Why we love it
Breathable and water-resistant design.
Long-lasting adhesive up to 14 days.
Skin-friendly and hypoallergenic.
Main highlights- True Adhesion - Careful application of the patch on dry, clean skin will result in 10-14 days of adhesion, however, adhesion duration will be less if skin is subjected to excessive moisture. Air uses edge-to-edge adhesive + a unique highly breathable non-woven patch material preventing fraying and sticking even in water. These patches are designed not to move or lift.
- Thinner and Lighter Than Ever - Our thinnest sensor patch ever, Air is made from non-woven micropore and is stretchier, thinner, and more durable than spandex or cotton patches. So light you’ll forget you’re wearing it!
- Kind to Skin - These Libre 2 sensor covers are latex-free and kind to skin. Air patches grip to your skin without causing irritation. Latex-free, hypoallergenic and made with a medical-grade skin-safe adhesive.
- Keeps Your Device In Place - A longer adhesion time means fewer patch changes. And when it’s time to change patches, you can leave your device in place. Air molds to the shape of your device faster due to a fabric non-stick section and helps extend the life of your Libre.
- For an Active Lifestyle - breathable and water-resistant, Not Just A Patch ‘Air’ keeps your CGM device in place without moving whether you’re working out, sweating, or swimming. Protects your Lingo CGM and Libre 2 sensor.
