Insulin Pump Belts for Teens & Adults – Dia-Belt M/L 61–120 cm

Dia-Belt M/L – insulin pump belts for active teens and adults

The Dia-Belt M/L is a soft, adjustable insulin pump belt for teens and adults, designed to keep a tubed insulin pump close to your body while you move through work, sport and everyday life. Worn around the waist or hips, the belt holds your pump in a stretchy pocket so it stays secure and comfortable under clothing.

Made from elastic, breathable fabric, Dia-Belt M/L fits waist sizes of about 61–120 cm. The flexible waistband adjusts to your body shape, while flat seams and a smooth inner surface are gentle on the skin. A discreet opening at the back of the pocket lets you route the infusion tubing under your clothes, helping reduce snagging, pulling and accidental disconnection of the pump.

Dia-Belt M/L models are available in solid colours and printed designs, so you can choose a discreet belt for the office or a more colourful option for sport and leisure. Lightweight and low-profile, the belt can be worn comfortably under everyday outfits, sportswear or pyjamas, day and night.

Compatible with popular insulin pumps

Dia-Belt M/L is suitable for most tubed insulin pumps used by teens and adults, including Medtronic™ MiniMed™, Tandem t:slim X2™, YpsoPump®, DANA-i® and other pumps with similar dimensions. If you are unsure whether your pump will fit, our team is happy to help you choose the right size and model.
