...never heard of these nalgene water bottles. What's about access to their info/getting them? I'd been using Campy water bottles. whatever I'd use ---- when the day ends, i preferrably dump the leftover. I consume Gatorade only. Never use it for over 2 days. Very rarely on a 2nd day. And when I consume it all in one day; always wash it out, only with biodegradeable dishwashing soap.
