Polar Bottle Insulated Sport
Well, maybe just a little bit more. The insulated sport bottle keeps liquids colder than a standard water bottle (thanks to its double-wall construction) and the drinking valve is removable to facilitate more thorough cleaning. It’s also both freezer and dishwasher safe.
When I reviewed the original model, I noted that the plastic felt especially stiff. It turns out that quite a few customers felt the same way, and Polar Bottle updated their design so that the new bottles are easier to squeeze.
The Insulated Sport bottles come in 12, 20 and 24 ounce sizes and retail for $10 to $15. Check out www.polarbottle.com
