Ive really down-sized my back-country toiletry kit:
Dr. Bronners
Small tooth brush and travel tooth paste (could for 7-10 days)
Travel pack of baby-wipes
TP and small bottle of hand-sanitizer in a Ziploc bag
Dental floss is in another kit and handy when you get that piece of food stuck in your teeth
its extremely handy.
A small container of Gold-Bond or Monkey Butt powder is a good idea depending on your activities. Ive used it for long road marches and it some very hot/humid hiking conditions.
Ive used a little alcohol rub on my feet which is good to dry them out if theyre wet and wrinkled from being immersed in water. I use to pack a small alcohol stove for field use and a cotton ball and some mineral spirits (stove fuel) worked great on the feet...drying them out and cooling them off.
Chapstick is a must in my kit and part of my EDC. More for protection than hygiene, but I consider it a part of my hygiene kit; Burts bees is my preference. I know its not an essential, but I keep a small pair of flat folding nail clippers (combination with Sliver Gripper tweezers) in my kit. I like to keep my nails trimmed
just a pet peeve, but a cracked or torn nail can hinder your ability to manage small item tasks and could potentially get infected.
Thats pretty much it. I use my cravat/banana as a washcloth and when it gets to the nastier crevices, Ill use the baby wipes. I dont pack a towel often as Ill dry pretty quickly in the south. I do my major washes at night right before bed, so its less of an issue unless its really cold temps.
Field hygiene and sanitation is critical to maintain your health and sanity. Ive spent many a tactical field exercise where your daily routine was to take care of your teeth, feet, pits and crotch. I was getting really good at taking a full sponge bath, shave and brushing my teeth using a full canteen of water and canteen cup (jet boil used to heat the water for the mandatory field shave).
