The best and cheapest way to get water on the trail is to buy Aquatablets in a pharmacy in Kathmandu. They are really cheap, come in an easy to use pack. JUST SQUEEZE OUT 1 TABLET , wait 30 min and drink. I am currently using a 2 step process that is a bit of a hassle. I have 2 water bottles, one is sanitizing and one I'm drinking. Easy. Every little village has a spigot that you are free to use. No need to carry a heavy Camelback. Sorry honey, it was a great gift. I'll use it on day hikes.
