Hi, I believe that for a 1ltr nalgene widemouth, I should order the parka #1. Is that right?
I'm sure you've already answered this for yourself, but yes, the parka pictured in the middle (short and stout) works for a 1L nalgene. I also like the Hunersdorf 1L bottles - they are a softer plastic that seems to work better in extreme cold, and the tops are a bit more mitten friendly.
Enjoy the cold water!
Yes, #1 is correct. I ordered two OR #1 for my Nalgene 1L wide-mouths this spring and took them for a month on Denali, where they worked great. FYI it's a somewhat snug fit, so don't expect to be taking the bottle in & out of the parka a lot. This can get annoying because the mouth of the Nalgene doesn't really come up out very far when you want to drink from it. I ended up sliding the bottle up about 2 inches inside the parka when I wanted to drink, then pushing it back down to close the parka.
Oops. Sorry about my first response. I have the #2 parka, which will fit your bottle.
That sounds right to me. I have 32oz (same as a 1ltr) nalgene and a knock off brand that both fit my parka. By the way, the parka works really well for both keeping liquids cold or warm. It it a little hard to get a bottle out of the parka at times.
Here are specs from OR website.
This insulated bottle carrier lets you transport hot or cold liquids into the backcountry. It weighs much less than a thermos, but offers similar performance. A reinforced nylon strap with a hook and loop closure allows it to attach to any pack and an updated design fits most modern day water bottles.

#1 is what you need for the 1 liter widemouth Nalgene. That is what I have. It fits a little snug but it works.
Very great parka to keep your water warm when hiking in freezing temperature!
