2,000 votes for water bottles? Christ, you can't swing a dead cat without hitting a stack of water bottles in every store on the planet! You pepople must live in Patagonia--or some other place that Amazon can't get reach in two days!
Narrow mouth nalgene is useless, hard to clean, can't upgrade the cap, breaks easier, and looks ugly.
Get the wide mouth and buy an insert to make them easy to drink out of.
Hydroflask is incredable as well
For outdoors use - Id go with the Stainless steel Nalgene standard -- can sterilize water in it via fire ........and the Platy bottle as its so compact , takes up less room as the water is consumed , can be frozen etc .... you can even set it up as a bladder if you add some peices.
The Platy would also be handy as a 'Dirty ' water bag you could use to harvest water before filtering/sterilizing into your primary water container(s).
I cast my vote for the zebra bottle because when you're a very short person with a small frame road bicycle, NONE of the insulated 20 oz bottles will fit in the water bottle cages. I'm currently using a kids insulated water bottle which just showed up a year or so ago.
