Best 2 liter bottle
I know there is already a ton of reviews on this but I am compelled to give my rave anyway. This bottle holds 2+ liters, yet can be folded smaller as liquid is used, and weighs close to nothing. My Nalgenes mostly stay at home or only get used as a "pee bottle" since the day I got one of these. I took away 1 star due to the smallish fill opening which also makes it take longer to air dry after trips but that is not a big issue. Get it, you won't be sorry!
