Dia-Band Nightnday is the thinnest, softest model of our universal armband. It fits like a second skin over FreeStyle Libre, Dexcom, Medtronic Simplera Sync and Guardian sensors, Omnipod pods and most other devices on the upper arm, and stays discreet under clothes.
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 Nightnday is the thinnest, softest model of our universal armband. It fits like a second skin over FreeStyle Libre, Dexcom, Medtronic Simplera Sync and Guardian sensors, Omnipod pods and most other devices on the upper arm, and stays discreet under clothes.
Its thin, soft fabric is easy to forget under a sleeve or in bed. Two colours: Cream Dream and Black Dream. Sizes XS to 3XL.
The word customers use most is "forget": the fabric is so thin and soft that they forget the armband is there, under a sleeve or in bed. Customers describe it as discreet enough to go unnoticed.
It is a favourite in hot weather: customers say it keeps the sensor in place even when sweat would make it slide off, and that it washes well.
For a lace finish, see Dia-Band Spacy Lacy. For a narrower band, try Dia-Band Narrow, or browse all our Dia-Band armbands for adults.

Received very quickly and the product matches the order...the only downside is that there isn't a size larger than 3XL....
Reçu très rapidement et produit conforme à la commande...le seul bémol c est qu il n y a pas une taille au dessus de 3xxl....

Too tight, too elastic, too thick, unpleasant fabric
Serre trop élastique trop épaisse tissu pas agréable
Hello Evelyne,
thank you for your feedback and sorry for that first impression. The NIGHTNDAY is actually the thinnest in our entire range, so a feeling of tightness or bulk usually comes from sizing too small: the fabric stretches and appears denser. Write to us at info@kaio-dia.fr, and we'll offer you either an exchange for the correct size or a refund, whichever you prefer.

very good

This is a product I highly recommend for diabetics, especially those who transfer a lot; it provides support for the sensor.
C'était un produit que je recommande vivement pour les diabétiques surtout pour celles qui transfert beaucoup cela fait un maintien au capteur
This is what I've been looking for for a long time.
C est ce que je recherchais depuis longtemps

I'm very happy with this purchase and it fits so well that I forget I'm even wearing it... I recommend this product and this website 😊
Satisfaite de cette achat et il se porte tellement bien que j'en oublie qu'il est a mon bras......je recommande ce produit et ce site 😊
Good product. Pleasant fabric. The two retaining bands work well. I bought more. Used for an Omnipod Patch insulin pump.
Bon produit. Tissus agréable. Les 2 bandes de maintien fonctionnent bien. J’en ai racheté d’autres. Utilisé pour une pompe a insuline omnipod patch.
Great material, my son loves wearing it.
Tolles Material, mein Sohn trägt es sehr gerne
The 2XL Midnight Hawaii is a bit too loose for me. It will be nice for summer. This XL headband is noticeably tighter, but because it's super thin, it stays on solidly and protects about
2XL Midnight Hawaii jest dla mnie trochę za luźna. Będzie fajna na lato. Ta opaska XL jest odczuwalnie ciaśniejsza, ale przez to, że jest super cienka trzyma się solidnie i chroni ok
It's good, but it's better to order a smaller size; otherwise, everything is OK.
c est bien mais vau mieux commander une taille plus petite au si non tous ok
It delivers on its promises
hält was es verspricht
Very nice

Is quite good but drops one more, otherwise nothing to complain about
Is redelijk goed maar zakt nog eentje verder niks op aan te merken
Helps protect my CGM while golfing or playing tennis.
I measured for my slightly bigger bicep and the band came exactly the correct size and fit is superb and it’s that light and unobtrusive you can’t tell you’re wearing it. As I’m allergic to even hypoallergenic Plaster CGM Patches I was wanting a subtle cover for those occasions I may be doing something vigorous be it gardening/car repairs or mountain Biking to try help protect the CGM from getting snagged/pulled on by clothes or trees!
Love the armband
Perfect thank you
Parfait merci
It fits well, but the rubber makes itchy for sensitive skin. Thanks and best wishes
Es passt gut, aber Juckreiz bei feiner Haut beim Gummi. Danke und liebe Grüße
Great item..
Super teil..
