I saw the Auvi-Q featured in the NYT. It seems to be smaller and lighter than the epipen. It is about the size of an playing carding and about a 1/2 an inch thick. They haven't posted the weight on it, but it sure does LOOK lighter and less cumbersome.
Is it time for UL backpackers with allergies to rejoice?
