I haven't used a Nalgene in 20 years. I followed Ray Jardine's advice and just use spring water bottles. I use them a few times and then recycle them and get new ones. They weigh a fraction of the weight of the Nalgene and are nearly as indestructible. I've never had one break and have carried them mountaineering in some pretty inhospitable areas.
