Oh yes!!! He's been a type 1....So has had it his whole life...He's done this his whole life. Coolers like this are perfect, so the insulin doesn't go bad from the heat
We have this exact cooler but in blue. We use it just about daily right now. My fiancé is diabetic so we'll put, Ice pack or frozen bottles of water in the bottom compartment & both his insulin's in the top. Keeps them cold, but not so much that it hurts when he goes to use them
