The bag is super! Insulin pens have very good space. Also for the needles and the BZ-meter is enough space. By the cooling element, the insulin stays cool even at 30 degrees in the car. Since the bag has a belt loop can take this good on hikes, and has therefore always everything thereby, what you as a diabetic so needs. The bag has even a Schlüsselanhäger, in a Pack Dextrose has space. The bag is really worth its price and I can highly recommend.!
