So I will start with the list of things I already have saved from surfing this sub

EarPlugs: http://www.amazon.com/Etymotic-Research-ETY-Plugs-Protection-Earplugs/dp/B0044DEESS/ref=sr_1_2?ie=UTF8&qid=1418951680&sr=8-2&keywords=etymotic&pebp=1418951683220

These are great to put over your tent to keep the light and heat out in the morning so you dont wake up in a sauna at 7am

And finally, I will never attend another festival again without this stuff, it is a foaming body wash that does not require water. We use it at my work all the time for bed baths and whatnot, so I thought I would try it for a festival and it works quite well. It doesnt get you as clean as a normal shower but this and baby wipes can keep you feeling fresh the whole weekend (just dont use it on hair)
