Very good bottle

I really like the spout style - no fumbling around with a pull-top spout. The sides are pretty flexible and easy to squeeze. As far as insulation goes, it seems to be on a par with other insulated bottles. There is no magical solution to keeping ice and fluids cold longer than a couple of hours when the temp is in the 90s.
