Dia-Band Plain Colors is the plain version of our universal armband for glucose sensors and patch pumps.
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.
Materials and care
90% polyester, 10% elastane (SQD fabric)
Hand wash only, 30°C maximum. Do not bleach. Hang to dry. Do not iron.
Certification and traceability
CE marked and compliant with the Medical Devices Regulation (MDR 2017/745), and with the European General Product Safety Regulation in force.
Download the certificate (PDF)Dia-Band Plain Colors is the plain version of our universal armband for glucose sensors and patch pumps. The elastic sleeve has no clip, so it fits FreeStyle Libre, Dexcom, Medtronic Simplera Sync, Guardian, Omnipod and most other devices worn on the upper arm, holding them in place and helping protect them from knocks and peeling.
Fuchsia Flash, Hot Chili, Very Berry, Flamingo Blush, Lapis Lalu, Ginger Spice, Black Knight, Creamy White and MM Macaroon. Sizes run from XS to 5XL (39-42 cm arm circumference), for larger arms too.
Plain Colors is the most understated model of the range: one solid colour, no pattern, discreet under a sleeve or clearly visible if you pick Fuchsia Flash or Hot Chili. It is also the model that goes furthest in sizes, from XS to 5XL.
Customers keep it on in the pool, on holiday and in the shower, one even for powerlifting, and wear it every day, children included.
For brighter solid shades, see Dia-Band Pop Colors. Prefer a print? Try the neon tones of Dia-Band Fluo or the dark designs of Dia-Band Midnight, or compare every model in our Dia-Band armbands for adults.

Using it on holiday in Greece to protect my omnipod and libre 2 + sensor. Had worries about water and heat but so far so good
Imported from Europe to USA great service
Lightweight material, perfect for summer. Holds the sensor securely without being too tight on the arm.
I recommend it.
Matière légère, parfaite pour l'été. Maintient bien le capteur sans trop serrer le bras.
Je recommande.
Appreciated with the shipping service. Very fast . The band is great.
Hello,
I'm very happy with the armband, except that it looks longer in the photo on your app. It's a shame it's shorter. I recommend it because it prevents you from losing the sensor. Thank you very much.
Bonjour,
Trés contente du brassard sauf que sur la photos de votre application il et plus long . Dommage qu'il soit plus cour . Je le recommande car sa permet de ne plus perdre le capteur. Merci beaucoup.
Hello, I'm very happy because I tried everything and nothing held, and now my sensor won't come off. Thank you!
Bonjour je suis très contente car j'ai tout essayé et sa tenez pas et la mon capteur s'enlève pas merci
Very safe on the arm and protects the sensor when I am wet all day long. My arms are big, compared to the rest of me; with the right measurement I got the right size. It’s a beautiful burnt orange which fits nicely with my outfits.
Perfect, true to size

Good size, a little tight. Was able to stretch out elastic some for a better fit. When first out the package, there was a LOT of dye bleeding (black). even after one was, still bleeding dye. Hoping one more wash will help.
Overall, pleased. thank you.
Too high a price for this quality.
Zu hoher Preis für diese Qualität.

Great for swimming
Topp beim Schwimmen
It fits well on the arm
Il tient bien au bras
Very happy with my purchase.
The armband stays in place well and protects the sensor. Because I sweat a lot, my sensors frequently came loose in hot weather.
My only slight regret is that it's not waterproof. But I would recommend another model in the future.
Very good product.

Très contente de mon achat.
Le brassard tient bien et protège le capteur.
Ayant une transpiration abondante, mes capteurs se détachaient fréquemment par temps chaud.
Mon petit regret c'est qu'il ne soit pas étanche. Mais je recommanderais un autre modèle ultérieurement.
Très bon produit.

The product is a good system, but for me it's not long enough, so the sensor isn't protected.
Le produit est un bon système mais pour moi il est pas assez long, de ce fait le capteur n’est pas protégé

Great fit
Wish I had bought it much earlier
I'm sorry to say that during the day activities or night it is dropping down and causing my sensor to fall off
Thank you for your feedback! It sounds like the Dia-Band might be slightly too big, which could be causing it to slip down during activities or at night. Our team will get in touch with you shortly to help find the best solution or recommend a more suitable size.

Good evening, Madam, thank you for your feedback regarding our Dia-Band armband. Our team will contact you to find a solution. Best regards,

The elastic bands are a bit uncomfortable and cut in. This means that you can only pull the band towards the shoulder to a limited extent. The band should be a bit wider.
Haltegummis etwas unbequem, schneiden ein. dadurch kann man das band auch nur bedingt in Richtung Schulter ziehen Band sollte etwas breiter sein.
Hello and thank you for your feedback!
When using our Dia-Band cuffs, the sensor should not be positioned too high above the armpit, as otherwise the cuff will lose its effectiveness.
If you have any further questions, please contact us at info@kaio-dia.eu.
