I’ve been using this double-wall insulated bottle since last summer, and even after leaving it in my car for 10 hours on a 95-degree day, the water inside was cool and crisp. Let’s see a plastic bottle do that. (It also keeps drinks hot for up to 12 hours.) My favorite feature is the Autoseal lid. It opens with one touch, has a high flow rate and features a spout cover to keep out dirt and grime. Plus, the bottle is top-rack dishwasher safe, BPA-free and comes backed with a lifetime guarantee. $37; avexoutdoor.com
