The S’well bottle is insulated and made of double-walled stainless steel so that it can keep water cold even when left in a hot car and can keep tea warm even when left on a nightstand overnight.
The bottles have a sleek, metallic finish. The cap is made of BPA-free polypropylene with a silicone ring to vacuum seal the cap tight. The opening at the top is big enough that you can easily add ice cubes. Liquids can stay hot or cold for up to 24 hours.
The standard bottle holds 17 ounces and comes in seven colors. It retails for $35. There is also a 25-ounce version that is big enough to hold an entire bottle of wine, and a nine-ounce version that fits in a lunchbox.
Because stainless steel is safe, the bottles don’t need to be coated with a plastic liner, and there is no metallic taste. The insulation keeps the bottle from sweating so your hands stay dry as you drink. The bottles are not dishwasher safe, but should be hand-washed and air-dried.
Purchase of a S’well bottle helps support WaterAid, which provides safe water, hygiene and sanitation in impoverished areas of the world. For information, visit swellbottle.com.
