Sok It BotlSok Water Bottle Sleeve Insulated Neoprene Cover Fits 32oz Nalgene

I was looking for a solution to the condensation issue on my nalgene bottle, and this sleeve solved that issue. One thing to note- if the built-in loop bothers you (how it sticks up), if you actually add a carabiner it will flop over and get out of the way. I didn't think I'd like that feature, but after adding it, I found I preferred that method of carrying it over the nalgene cap loop. I would definitely buy this again.
