When my son asked me to carry his supply bag so he 'could be normal like everyone else' when we went to the mall one day, I went on a search to find him a small and manly type bag to carry his stuff in. I finally found a sling type backpack. I have looked and looked for something that wasn't girlish, but a lot of the supply totes out there for diabetics are really geared more for girls/women. You would think after this long of trying to find something I would just figure out how to make it lol. At home, I keep all of his stuff on top of the fridge in a basket and he comes and fills up when his supplies are getting low and he has a shelf in the fridge as well.
I also bought him clear plastic makeup bags to keep the short needles in and another one for his Lantus needles. He isn't on the pump and doesn't have an interest in it, although I wish he would be more susceptible to it he just doesn't like change very much.
His bag is similar to the one shown here at Target
