Am is the lightest possible treatment
Unless you wanr to pretend other people never take breaks, and thats total BS
Take your break when you get water, as most do.
Now, whats the lightest?
Or look at work done .
Carrying 2 lbs for 15 min, 3 x per day id still less overall work than 4oz for 10 hrs per day. Do the math.
As ive said many times, understanding am is key to efficient use. Virus and bacteria is dead in a minute. Giardia is deactivated 1000x in a few min. If you arent drinking sewage, you dont need to wait long. No one is worried about crypto either so forget the 4 hr .
My 2 wk supply of am weighs 1.2 oz in its little bottles. My water bottles are 0.93 oz dasani.
Someone who isnt going to carry water, isnt regardless of method. Someone that will, will. pretending otherwise is just pretending really. Just like pretending it has no weight cause it was drank instead of on back .
Funny to hear these claims but never seemed to be passed by these people with filters and steripens. Maybe they use similar justification for everything in their pack, and it ends up hvy. 4 oz for steripen, 2 oz for backup batteries, 6 oz for wide mouth nalgene, several oz for chemical backup too. Etc etc. All the while argueing they have the lightest system.
