For Freestyle Libre 3
Your sensor stays on. All 14 days.
Most sensor failures are not sensor failures - the adhesive lets go first. A breathable cotton overpatch cut for Libre 3, with a 16.5 mm adhesive ring that holds through showers, workouts and sleep.
Free US shipping over $35 - 25 patches per box
Full 14-day wear
Showers, workouts and sleep - the whole sensor cycle.
Cut for Libre 3
58 mm cover, 25 mm centre opening. Not a universal square.
Breathable cotton
Skin stays dry instead of trapping sweat under plastic.
Hypoallergenic
Latex-free acrylic adhesive, tested to ISO 10993.
The material
Breathable cotton. Not plastic film.
Cheap PU patches seal the skin. Sweat pools underneath, the edge curls, and by day four it is on your shirt instead of your arm.
- Skin breathes - sweat escapes instead of pooling
- Soft, flexible edge that does not curl
- Sealed, rounded die-cut - nothing to catch on a sleeve
The fit
A 16.5 mm grip on every side.
The 35 mm figure you see everywhere is the sensor, not the patch. Ours is 58 mm across with a 25 mm opening, which leaves a real adhesive ring instead of a thin lip.
- 58 mm outer diameter, 25 mm centre opening
- Sensor face stays completely clear
- Die-cut for Libre 3 and Libre 3 Plus
How it works
On in ten seconds.
Split backing paper means you can do it one-handed, on your own arm.
Clean and dry
Wipe the skin around the sensor with alcohol. Let it dry completely.
Peel half
Remove the smaller half of the split backing paper.
Line up
Centre the opening over the sensor and lower it into place.
Press 30 seconds
Smooth outward, then press flat. Body heat sets the adhesive.

Why it holds when others peel.
Most patches fail because sweat gets trapped, not because the glue is weak.

FAQ
Questions people actually ask.
Does it fit Freestyle Libre 3?
Yes. It is die-cut specifically for Libre 3 and Libre 3 Plus - 58 mm outer, 25 mm centre opening. Dexcom G7, Stelo and Omnipod sizes are on the way.
Will it affect my readings?
No. The centre opening leaves the sensor face completely clear. The patch only holds the sensor housing against the skin.
Can I shower and swim with it?
Yes. Water runs off the patch instead of creeping under the edge. Pat it dry afterwards rather than rubbing.
My skin is sensitive. Is it safe?
The adhesive is latex-free medical-grade acrylic, tested to ISO 10993-5 and ISO 10993-10. If you have a history of adhesive reactions, test a single patch first.
How many patches will I need?
Most people use two to three per sensor cycle, so a 25-pack lasts roughly four to six months.
What if it does not stick?
Nine times out of ten the skin was not fully dry. Try one more with a proper alcohol wipe - and if it still fails, contact us and we will make it right.
