I've found that a PolarBottle will buy you a little more time than a standard, non-insulated bottle. I did a little experiment last December...

Temperature units are degrees Fahrenheit.

Code:
Elapsed      Water Temp        Outdoor
  Time    Polar  | Generic         Temp
---------------------------------------
0:00       106        106            5.2
0:40        79         61            6.0
1:25        59         33            6.8   Ice forming on top of generic bottle
2:10        39         31            7.7   Top/Sides of generic bottle frozen
