Our most discreet Dia-Style for the FreeStyle Libre 3 comes in a single slate grey. The clip is shaped for the Libre 3 sensor, also used by the Libre 3 Plus and the Medtronic Instinct, and the strap tightens to your arm for work, sport or sleep.
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.

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 |
