This Dia-Style armband is made for the Medtronic Simplera Sync sensor. Its rotating clip turns inside the band to match the angle of the sensor on your arm, and the 2.5 cm strap holds it in place without adhesive.
Show moreHow do I find the right size?
Wrap a tape measure around your arm where you usually wear the sensor. Measure your arm only: do not measure over the sensor or the pod, their thickness does not count. Then pick the size whose range contains your measurement: S 23 to 29 cm, M 26 to 33 cm and L 29 to 38 cm for adults, XS 18 to 25 cm for the Dia-Style Kiddy.
The strap is adjustable, so a measurement that falls in two ranges works either way: take the smaller size if you like the band snug.
How to wear it
Slide the armband up your arm, turn it so the clip sits over the sensor, and press the clip down around it: the sensor is held by its edge, nothing presses on it. Tighten the strap with the slider until it feels snug, not tight. On the Dexcom G7 and Simplera Sync versions the clip rotates inside the band, so it lines up with the sensor whatever angle you applied it at.
Keep it on for sport, in the shower and in the pool. Afterwards, dry the clip with a towel and keep it away from heat sources such as a hair dryer or a radiator, which could warp it.
Compatible devices
Each Dia-Style has a clip made for one sensor shape, so it fits the devices listed here only. For another device, choose the universal Dia-Band.
Materials and care
Elastic strap 2.5 cm wide, 77% polyester and 23% elastane. Clip in PLA, adjuster in ABS.
Hand wash only, in lukewarm water. Hang to dry. Do not iron. Keep the clip away from heat: no hot water, no dryer, no hair dryer, no radiator, it could warp. After the shower or the pool, dry it with a towel.

The right size keeps your adjustable Dia-Style armband in place all day without slipping or feeling tight. Sizes are based on the circumference of your upper arm, where the glucose sensor or patch pump is worn. Each Dia-Style has a clip that fits the size of your sensor or pump: first choose the model made for your device, then your size.
| Size | Arm circumference (cm) | Arm circumference (in) |
|---|---|---|
| S | 23-29 cm | 9.1-11.4 in |
| M | 26-33 cm | 10.2-12.9 in |
| L | 29-38 cm | 11.4-14.9 in |
The strap is adjustable, so the ranges overlap: if your measurement falls into two ranges, both sizes will fit. Take the smaller one if you like a snug fit. Available sizes can vary by model, so check the sizes offered on each product page. See all Dia-Style armbands for adults.
| Size | Arm circumference (cm) | Arm circumference (in) |
|---|---|---|
| XS | 18-25 cm | 7-9.8 in |

So far, I’m very happy with it. However, I haven’t been using it long enough yet to give a full review.
bisher bin ich sehr zufrieden damit. Aber die Nutzdauer ist aktuell für eine vollständige Bewertung zu kurz.
My 12-year-old grandson is very happy with it: during his self-defence classes, the armband holds his sensor very well.
Mein 12 jähriger Enkel ist sehr zufrieden , bei seinen selbstverteidungs Sport hält das Band seinen Sensor sehr gut.

Thank you so much!
Super merci beaucoup
Perfect, excellent quality. I had previously bought two Dexcom G6 sensors, but due to a pump replacement, we also had to replace the sensor. The other two are still in perfect condition. Highly recommended, great quality and price.
Perfecto, muy buen material, y ya antes habia comprado 2 del dexcom g6, que por cambio de bomba nos toco tambien cambio de sensor, y los otros los tenemos aun en perfecto estado.

I purchased the Medtronic Simplera Sensor with Adjustable Armband and Rotating Clip for my 14-year-old son. The size Small (23–29 cm / 9.1–11.4 in) fits him perfectly. The armband is made of high-quality materials and fits the Simplera sensor securely, helping to prevent it from coming off—especially on hot summer days or during swimming.
When the delivery to Slovenia was delayed by a few days, I reached out to Kao Dia customer support. They responded promptly and professionally, which I really appreciated.
I highly recommend both this product and the Kao Dia online store.
👌👍 Fits Simplera perfectly, great for sports! The inner part adapts to the sensor, definitely recommend it! Comfortable to wear 👍😀
👌👍 Passt genau für Simplera, super beim Sport! Der innenteil passt sich dem Sensor an, klare Kaufempfehlung! Angenehm zu tragen 👍😀

Great product, would gladly buy again
Super Ware, gerne wieder
It's perfect. The case fits the sensor very well and the rubber is soft and wide so as not to cause discomfort. A 10 purchase!
Es perfecto. La carcasa se ajusta muy bien al sensor y la goma es suave y ancha para no causar molestia. Una compra 10!
Made with quality material. The only flaw if it can be defined as a flaw is that the sensor has a square shape and when it is applied to the arm you do not have the precision to put it perpendicular to the band served by the rotating housing
Fatto con materiale di qualità. L'unico difetto se si può definire difetto e dato che il sensore ha una forma quadrata e quando viene applicato sul braccio non si ha la precisione di metterlo perpendicolare alla fascia servita l alloggio girevole
Great product!
Ottimo prodotto!
