Proper hydration is key, well, always, but especially when you’re going to be spending your day out in the heat. Stay on top of your liquid consumption with this stainless steel beauty. The matte black, stainless steel body is fully insulated, to keep its contents ice cold — or steaming hot, if that’s more your style — and fitted with an airtight, screw-on cap. Fill ‘er up with water, or beer (two and a half bottles, to be exact), or, if you’re feeling particularly festive, a cocktail, and take a big ol’ swig any time you’re in need of refreshment.

Hand wash with warm, soapy water and a bottlebrush to extend the life of your container’s paint. Drain and dry in your dish rack with the mouth downward so water can drain out. Also recommended to use an old-fashioned cleaner: diluted vinegar or water and baking soda.

Mizu is the maker of eco-friendly reusable water bottles made for the active environmentally-conscience individual. The brand is named after the Japanese word for water, and they’ve partnered with the likes of Nixon, Volcom, Burton, and more.
