What? Why?
> matches ... lighter
Why both? I just bring two lighters
> Selfie stick ... hiking poles
I find the more stuff I bring, the more frustrated I get unpacking and packing each night and day. Of course there’s the weight thing, too, but anyway try to pack your things in cloth or plastic baggies for separation. I use the zippered pouches that are sold for this purpose in luggage when traveling.
Also don’t forget a trash bag!
> bells
This is great if you are hiking where bears are active. We call them bear bells for this reason.
