I have to admit, I was a bit skeptical when Polar Bottle sent this insulated bottle in for review. Not just as to whether it was insulated enough to make a noticeable difference, but whether I would really care. The answer is yes and yes. I was also surprised to learn that the Polar Bottle is made in the USA.
I didn’t conduct any controlled scientific experiments to determine if the Polar Bottle in fact keeps liquid twice as cool as typical bottles, but it does keep your drink cool. And once the temperature reaches the high 80′s and I’m going to spend 5 hours out on my bike, it’s kind of nice to have some cool water available. The Polar Bottle has double wall construction which forms a barrier of air between the liquid and the environment. I’ve had my drink stay cool for more than five hours in steamy mid-August weather. The construction also makes the bottle seem more sturdy than typical cycling water bottles. Or perhaps it’s the particular LDPE plastic they use.
