Dia-Band Narrow is a slimmer version of our universal armband, about 8.5 cm wide compared with roughly 11.5 cm for the standard Dia-Band.
Show moreHow do I find the right size?
Wrap a tape measure around your arm where the band will sit. Measure your arm only: do not measure over the sensor or the pod, their thickness does not count. Keep it snug but not tight, then pick the size whose range contains your measurement.
Under 22 cm you are in the kids range, from 22 cm up you are in the adult range. If you fall right between the two, take the adult size: the band stretches down more comfortably than it stretches up.
How to wear it
Slide the band up your arm until the sensor or pod sits in the middle of the fabric panel. It should feel snug, not tight: you should still be able to slip a finger under the edge.
Keep it on in the shower and in the pool. The fabric dries quickly and holds the sensor against your skin. It does not seal the sensor, which water-resistant CGM sensors do not need anyway.
There is no adhesive, so nothing to peel off and no glue rash. Wear it at night if your sensor catches on the sheets.
Compatible devices
Your device is not in the list? The Dia-Band holds it anyway. It is a sleeve, not a clip, so it works with every sensor and every tubeless pump on the market.

Download the certificate (PDF)Dia-Band Narrow is a slimmer version of our universal armband, about 8.5 cm wide compared with roughly 11.5 cm for the standard Dia-Band. It still covers your glucose sensor, whether FreeStyle Libre, Dexcom, Medtronic Simplera Sync, Guardian or another model, while taking up less space on the arm and under short sleeves.
Black Knight, Breton Bleu, Ginger Spice, Maui and Midnight Madrid. Sizes XS to XL.
At 8.5 cm wide, Dia-Band Narrow leaves more of your arm free than the standard band, which is why many customers choose it when they move a lot. In their reviews they mention football, martial arts and dance, and wearing it at work when their arm keeps knocking the sensor. Others keep it on at night for peace of mind.
Several customers find it far more comfortable than adhesive patches: nothing sticks to the skin, so nothing pulls when you take it off.
For a super-thin fabric, see Dia-Band Nightnday. For a lace finish, try Dia-Band Spacy Lacy, or browse all our Dia-Band armbands for adults.
The right size keeps your Dia-Band armband in place all day without slipping or feeling tight. All sizes are based on the circumference of your upper arm, where the glucose sensor or patch pump is usually worn.

I received it a few days ago and tested it for a day – no problems. I’ve ordered some more to wear when working outdoors, such as when I’m chopping wood or tending to the garden.

Meets my expectations
Conforme à mes attentes
I'm very happy with my order. The armband is a perfect flesh color.
It's exactly what I was looking for and it's very comfortable.
I'm going to order another one.
I find the material to be good quality and I hope it won't shrink when I hand wash it.
Je suis très satisfaite de ma commande. Le brassard est parfait couleur chair.
il correspond exactement à ce que je cherchais et il est très confortable.
Je vais en recommander un autre.
Je trouve la matière de bonne qualité et j'espère qu'il ne va pas rétrécir quand je le laverai à la main.
Perfect, it stays on the arm very well without slipping.

It slips down the arm and doesn't stay in place.
Glisse sur le bras ne reste pas en place
Hello Didier, thank you for your feedback and we're sorry the armband isn't staying in place.
When it slips, it's usually because the size is a little too big: a smaller size fits the arm better and stays put.
We'd be happy to exchange it.
Email us at info@kaio-dia.fr and tell us the circumference of your arm where you wear it, and we'll find the right size together.

Fast shipping and nice product
Envoi rapide et produit sympa
The XL size I chose is quite small for my arm, which I checked twice without tightening it. Perhaps you could make an XXL version; I think that would be a good idea. Otherwise, it's a very good product that I appreciate. It's much more comfortable than the expensive adhesives from the pharmacy that pull a lot on the skin when you finish using them. Thank you for this innovation.
La taille xl que j ai choisie est assez limitée pour la taille de mon bras que j avais pourtant vérifiée deux fois sans serrer. Peut-être pourriez vous faire un modèle xxl, je pense que ce serait judicieux, sinon très bon produit que j apprécie, cela est bien plus confortable que les adhésifs chers obtenus en pharmacie qui tirent énormément sur la peau lors de la fin de leur usage
Merci pour cette innovation
Hi Jean-Marc, thanks for your feedback, we're delighted you like the product! You actually ordered the Dia-Band Narrow, which goes up to size XL. For larger arm sizes, our standard Dia-Band goes up to 5XL. Many prints are available here: https://fr.kaio-dia.eu/collections/brassards-protection-capteurs-de-glycemie. See you soon!

Nice and comfortable to wear and saves sensor from falling off really like wearing it
The only downside is the tracking information, as the data wasn't updated.
The ordering process and the variety on the website were great 👍.
...
Das einzige was zu bemängeln ist die Sendeverfolgung wo die Ware ist weil die Daten nicht aktualisiert wurden.
Der bestellvorgang und die Vielfalt auf der Homepage waren super 👍.

Pretty nice material!! Fits well!
I was looking an armband with quality and reliability .I have acquired such with your product Iso happy with it's comfort and security.Thankyou.
Excellent customer service by the international team. Only issue was unclear Bulgarian post instructions. That the shipment will come via post not courier. Confusion comes as my home address was requested with the order and tracking of the shipment was not user friendly to understand where to pick up the shipment from (only said to pick up from place of pickup)...it took me days to figure out there was only a postal code listed as clue in the tracking so it means from a nearby post office. No note or communication from the Bulgarian post office was delivered to inform on the shipment.
The fabric is excellent, but it's a little short. It could have been 2-3 centimeters longer.
Ottima come tessuto, però un po' corta. Poteva essere 2/3 centimetri più lunga
Good evening, Giovanni,
Thank you for your feedback. We have the standard Dia-Band (not short) that measures approximately 11.5 cm in length. If you would like to exchange it, please email us at info@kaio-dia.eu.
