Here is my backpacking toiletries list:
Hotel bar soap, tiny sponge, lidded bowl for taking wash water to my tent; lip balm; .5oz teatree oil (or eucalyptus or peppermint); tiny tube of general salve; travel toothbrush; sometimes a tablespoon of baking soda for tooth powder + deoderant; large bandaids that can be cut to size; roll of stretchy gauze; dental floss for teeth and thread; comb.
This is one category where the moniker, “If I don’t have it, I don’t need it” is useful. Going without something for a few days helps me clarify what I want vs what I need.
I want to love everything I carry! 3rd of my 5 essentials is “Love my gear”!
