Whoa there Helen! Not insulated. Just those flimsy little clear bottles
that bottled water comes in works best for me. I think one reason that
I like drinking out of the bottles is because I swallow less air when I
drink. This keeps the bloating down. My doctor said that WARM water is
much better to keep digestion moving than cold. So I just sip away on a
bottle of lukewarm water and think to myself (with a flip of my hair)
"I'm being European today!" as I drink my un-iced beverage.
