I'm about to embark on my first real camping trip so I've asked my brother A.J. an avid camper, hiker, and backpacker for some advice on what camping essentials we will need.
Propane Lantern

PVC free Solar camp shower

Dr. Bronner's organic biodegradable soap

Sea to Summit Clothesline

Biodegradable Toilet Paper
Of course, there are many more things needed for camping; a tent, tarp, sleeping bag, air mattress, towels, crockery, toiletries, ax, dutch oven, etc.
