i am guilty of having a larger than usual PFAK. but thats also because i usually hike with 2 dogs and people who aren't prepared for even a blister. honestly, i'd rather deal with a little extra weight or bulk and have something when you need it. for example, i also carry a small bottle of sterile eye wash which i can use for wound irrigation if need be. some might think this a needless addition but i like having that option in my PFAK. nothing in my kit makes me falsly confident though. my hope is to never have to use any of it.
