Anyone who needs to have their insulin pump with them at all times is looking for a solution that is both practical and comfortable. That's exactly what our insulin pump bags (also often written as insulin pump bag) with a flexible belt offer: small, lightweight, secure on the body, compatible with all common pump models and CGM readers.

Flexible belt for all sizes
The elastic belt is very stretchy and adjusts to a waist circumference of 50 cm to 130 cm. This makes the bag suitable for all age groups, from toddlers to adults in XXL size. The pump stays securely in place, even during movement, sports or play.
For very young kids with diabetes (from around 1 year old), there are also special versions with a shorter belt for a waist circumference of 50 to 80 cm and child-friendly designs, which you can find in the Diabetes Kids World.
Universal fit for pump and reader
Regardless of which insulin pump you use, the bag fits all common models up to approximately 12 × 7 cm in size. Specifically: Medtronic MiniMed (including the current 780G), Accu-Chek Insight or Spirit, Mylife Ypsopump, Tandem t:slim X2 and Dana. CGM readers such as the Freestyle Libre Reader or Dexcom Receiver also fit inside, as does the Omnipod DASH PDM.
Alternatively, you can carry the pump in a smaller pump case with clip or belt if you don't want a belt. Both carrying options are available in the range, along with bra pump cases and pump underwear for women.
With slit for the catheter tube
A small slit in the back of the bag guides the catheter tube through safely and discreetly. This prevents the tube from being pinched by the zipper. A small design detail that makes all the difference in everyday life.
Version with viewing window for reading the display
If you want to read the current basal rate or remaining insulin amount on a pump with a display without having to take the pump out of the bag, choose the version with a viewing window. The viewing window is clear and shows the pump display, which is especially practical in everyday life, during sports and for parents of kids with diabetes.
The viewing window versions are also available for all pump models and in several designs; see the selection below.
Handmade in the Zuckerschmuck studio
We design the bags ourselves and have them made to a handmade quality standard. Made of cotton with a secure zipper, they can simply be cleaned by hand at 30 degrees when needed. We use the bags ourselves every day. All design improvements come from real-world wearing feedback.
The ideal solution for outfits without trouser pockets
With skirts, leggings, dresses or trousers without pockets - clothing that leaves insulin pump users no place for their pump - the waist pouch is often the only practical solution for carrying the pump on the body. It sits discreetly under clothing or can be worn visibly; both work.
Frequently asked questions about the insulin pump case with belt
Which pump models fit in the bag?
All common insulin pumps up to approximately 12 × 7 cm fit inside: Medtronic MiniMed (all models including 780G), Accu-Chek Insight or Spirit, Mylife Ypsopump, Tandem t:slim X2 and Dana, as well as the Omnipod DASH PDM. For special models or newer generations, contact us in advance and we'll check the fit.
What belt sizes are available?
The elastic standard belt fits waist sizes from 50 to 130 cm, from toddlers to adult XXL. For the very smallest children (from around 1 year), there are also special versions with a shorter belt for waist sizes from 50 to 80 cm in the Diabetes Kids World.
Is the bag also available with a viewing window?
Yes, in several designs. With a viewing window, you can see the basal rate or remaining insulin amount directly through the bag on pumps with a display, so you don't have to open it. Recommended models: Blue jeans with viewing window, Pastel with viewing window or Black jeans with viewing window.
Does the zipper pinch off the catheter tubing?
No. There is a small slit on the back of the bag through which the catheter tubing is safely routed outside, not through the zipper. This is the key functional difference from generic waist bags used for sports.
How do I clean the bag?
On a 30-degree hand-wash cycle. Then air-dry. The zipper and stitching withstand many washes; of course, remove the pump before the first wash.
Does a CGM reader fit inside too?
Yes, alongside the pump or as a standalone bag. Freestyle Libre reader, Dexcom receiver and the Omnipod DASH PDM all fit the same size. If you only want to carry the reader (without a pump), there are more compact options in our waist bag category.
Is the insulin pump case waterproof?
The belt bags are made of cotton. For swimming, bathing and sports, there is a separate insulin pump case made of quick-drying nylon material. Whether your pump itself is water-resistant is stated in the manufacturer's instructions.
