The other Polar bottle is a traditional-type water bottle called the Blue Big Bear 24 ounce water bottle. Again, this one is insulted — a great feature to have if you do any sort of outdoor activity and want to bring a reusable bottle. Two walls of plastic keeps your water cool twice as long as traditional bottles, Polar says, and I agree. The drink spout on top gives you a controlled amount of water, which is great for drinking while you’re running or walking without spilling it all over yourself. It’s on the taller side of bottles at 10.5 inches, but it fits perfectly in most bike water bottle cages. The bottle is free of BPA and Phthalate. The Blue Big Bear retails for $11.99.
