Name: S'well Bottle (17 ounces/500 milliliters)
What it is: An eco-friendly, reusable water bottle designed for style and portability. The bottle is made with double-walled, food-grade stainless steel, so it doesn't require the plastic liner found inside most aluminum containers. The cap is made of BPA-free polypropylene and has a latex-free silicone ring to create a vacuum seal. The S'well bottle can keep cold beverages cold for 24 hours and hot beverages hot for at least 12 hours.
The good: Though this bottle is bulkier than a collapsible plastic bottle, I enjoy the versatility of having hot or cold beverages, such as hot tea or cold water. I was shocked how cold my water was after I'd left the S'well bottle in my car in the hot sun for several hours. Though the company makes a larger version for carrying wine, I haven't tested mine with alcohol.
The bad: It's heavier than a collapsible plastic bottle, and you can't put it the freezer, but the manufacturer did make the bottle's mouth wide enough to accept small ice cubes. I wish S'well offered an attachment to force ice cubes into the bottle's mouth. My solution has been to use the S'well cap to force a cube down if it's stuck in the bottle's neck. But I seldom add ice because S'well keeps a drink cold enough anyway.
