Keep the cold things cold and the hot things hot for a really long time! S'well bottles are easy to put ice in, reusable/terrific for the environment, and the 25 oz. bottles hold an entire bottle of wine...just in case you were wondering. Here are the pretty little details:
• Triple-layered, vacuum-sealed insulated construction / keep cold beverages cold for up to 24 hours and hot drinks hot up to 12 hours
• Made with food-grade stainless steel
• Copper wall layer - so the outside doesn't "sweat"
• BPA free and reusable • Hand wash only
