I'm in the market for a new water bottle to EDC. Usually, half a litre would suffice, but size isn't what concerns me the most right now. I read a bit on the subject and it looks like Camelbak and Nalgene are some high quality bottle, but I can't decide between the two. Which ones do you guys have and how do they cope ? Any leaks ? What other brands would you recommend ? *I choose Camelbak and Nalgene because those are available in Romania, but if you recommend other brands, I'll check for availability.
