My son would put phone in pocket and he would loose it
Thank you for your review Gay!
The extender made my SPI belt more versatile in that I can wear it slung over my shoulder comfortably or wear it loose around my waist or hips. Highly recommended!
Works very well really helps keep my diabetes pump from moving and keeps it out of the way !!
The extender allows a comfortable fit for a big guy.
I am not a runner. That said, I'm a soon to be 60 yr old woman with diabetes. I bought the belt extender with my first diabetic Spibelt purchase. So glad I did. The belt alone is snug, but fits, but having the belt extender allows me to wear the belt, where I don't even know I have it on, which is great, because lately I wear my Spibelt 24/7 as diabetes is a 24/7 disease.
