My son and I both have to carry an epi-pen and it seems that finding just a small holder for them in near impossible. I saw this belt and figured that it was worth giving a chance to see if we could fit just the epi-pen and some Benadryl in it without having to carry a bigger, bulkier bag while we were out doing things. It has worked perfect for that. It is fully adjustable so it fits his tiny waist as well as mine. It is also the perfect size to carry exactly what we have to without being bulky or uncomfortable. Given that it is so small, we even have the option of hiding it under our shirts so that everyone doesn't know that we are carrying anything. It really is the perfect carrier!
