Epi Pen

Tori • I`m a 21 yr old college student at SFA.
I just recently had an allergic reaction to something and now have to carry an epi pen on my person. I live in Texas and am involved with a college marching band so I have to be outside a lot. I know the epi pen can't get too hot so I was wondering do yall have suggestions on how to keep the epi pen with me even in the heat?
