I bought this 3 months ago for my 7 year old diabetic son. It’s a perfect size for a kid and also fits me. He’s found it comfortable and hasn’t complained. He wears it everyday to school and all weekend. There’s an intentional hole in the back for pump tubing, which is great. However, the fabric has started tearing where the hole is located. My son doesn’t have a pump, so we haven’t even been putting tubing through the hole. I now need to purchase him a new fanny pack since this one is tearing, and I will not be purchasing this brand again. It’s just too cheaply made.
