Dia-Band Spacy Lacy is the lace version of our universal armband.
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 Spacy Lacy is the lace version of our universal armband. Like every Dia-Band it has no clip: the sleeve fits FreeStyle Libre, Dexcom, Medtronic Simplera Sync and Guardian sensors, Omnipod pods and almost any device on the upper arm, keeping it in place under a dress, a blouse or on a night out.
Black, White, Nude, Navy, Shock Pink, Purple, Neon Yellow and Red. Sizes XS to 3XL.
Spacy Lacy is the lace Dia-Band, in eight colours from Black and Nude to Shock Pink and Neon Yellow. Customers treat it as a beauty accessory they match with their outfits, and say the lace hides the sensor well while feeling soft and light.
One customer says it makes her feel at ease when people look at her arm, and another notes it does not bunch or roll up. Others say the sensor no longer comes off while they get dressed or undressed.

Very pretty black lace armband, I love it.
But it doesn't stay in place because it slips.
I ordered another style.
Tres joli brassard en dentelle noir , j'adore.
Mais il ne reste pas en place , car il glisse
J'en ai recommander un autre modèle.
Beautiful and very functional band, it fits perfectly and above all it doesn't crease or roll up. Congratulations!
Fascia bellissima e molto funzionale, aderisce perfettamente e soprattutto non si increspa e non si arrotola. Complimenti
Great idea! Perfect for everyday use!

Practical and pretty
Pratique et joli
Looks great on, but I dont know if this design will keep the sensor in place, as its lace.
Love the look of it. Hides the sensor really well.
We forget we're wearing an insulin pump and a sensor.
I love lace headbands; they're my go-to beauty accessory that I can coordinate with my outfits.
On oublie qu’on est porteur d’une pompe à insuline et d’un capteur
J’adore les bandeaux dentelle cnest mon accessoire beauté que je peux accorder avec mes tenues
Tres joli
Excellent product, I highly recommend it. Very practical, with many options… very fast delivery, and they even exchanged it because it was too small. I returned it and they automatically sent me another one with a return label at their expense. It's really great, I'm very, very satisfied with the product. Well done!
Très bon produit je recommande , très pratique , avec de nombreux choix … livraison très rapide , et changement car il était trop petit je leur ai renvoyé et ils m’ont envoyé automatiquement un autre avec étiquette pour renvoie à leur frais c est vraiment très bien je suis très très satisfaite du produit Bravo

Highly recommend company
The port is nice and soft, easy to install, it holds my sensor well.
Le port est agréable et doux, facile à installer, il maintient bien mon capteur.
Fits well, stays in place
Taille bien reste bien en place
I had imagined the band would be a bit thinner, and unfortunately, it feels somewhat scratchy against the skin. Furthermore, there were major problems with the delivery. I inquired several times, and the item was shipped a total of three times before it finally arrived.
Ich habe mir das Band vom Material etwas dünner vorgestellt und es fühlt sich auf der Haut leider etwas kratzig an. Zudem gab es große Probleme mit der Lieferung. Ich habe mehrmals nachgefragt, der Artikel wurde insgesamt drei Mal verschickt bis er endlich bei mir ankam.
Hello Alexandra,
Thank you for your feedback. Regarding the delivery: Delays of this magnitude are unfortunately the responsibility of the shipping provider and beyond our control once the package has left our warehouse. We offer several shipping options at checkout, including faster and trackable options. We recommend choosing one of these options for future orders if delivery time is critical.
Regarding the material: The band is intentionally designed with a firm grip to ensure stability and durability on the body. However, should it not meet your expectations, please contact us directly, and we will find a solution.
Sincerely,
Kaio-Dia

Super, ça tient vraiment bien.
A little small but very pretty
Un peu petit mais très joli
Arm band arrived promptly and was of excellent quality.
Very practical. Not a single sensor came loose. Easy to wash and dry. Lightweight and flexible. You forget you're even wearing it. Discreet yet stylish.
Tres pratique. Pu un seul capteur decollé Lavage sechage dacile. Leger souple. On l oubli de suite. Discret et fantaisie malgre tout
Finally, sensors that last more than a week! Amazing!
Enfin des capteurs qui tiennent plus d'une semaine trop bien
Very good service yet again
Holds well 👍 and very pretty too 🥰
Tiens bien 👍 et de plus très jolie 🥰
The armbands are very practical because they hold the sensor in place; there's no longer any danger of it being pulled off while getting dressed or undressed.
Les brassards sont bien pratiques car ils tiennent le capteur en place , plus de danger de l'arracher en m'habillant ou en me de s'habillant
Fast delivery, stays in place

Mycket bra
I regret not buying them sooner.
Perfect fit.
I feel super comfortable and less self-conscious when people look at my medical devices.
The lace adds a flirty touch.
Je regrette de ne pas avoir en avoir acheté plus tôt
Taille parfaite
Je me sens super a l'aise et je suis plus mal a l'aise lorsque les regards se posent sur mes dispositifs medicaux.
la dentelle ajoute une touche coquette
Looks a bit like a mourning armband. Should have made it longer to give a more glamorous look.
Ressemble un peu à un brassard de deuil. Il aurait fallu le faire plus long pour qu’il donne un aspect plus glamour.
Chic and easy to wear
Chic et facile à porter
Love it
Too small, I measured the arm, take a size above
Trop petit, j’ai pourtant mesuré le bras, prenez une taille au-dessus
