When the summer heat kicks in, it can be difficult to keep a water bottle cold. No matter how many ice cubes are dumped in there, it all turns into hot water within an hour.

Takeya, a drinkware company, has developed an insulated, stainless steel water bottle that keeps beverages cold or hot all day long. Owners can enjoy up to 40 ounces of cold water on the go, whether it’s on a hike or in the gym.

The bottle uses a double-walled, vacuum-insulated design to keep the contents inside at a different temperature from the outside. Cold beverages stay chilled for up to 24 hours while hot drinks retain their heat for up to 12 hours. Regardless of the temperature inside the bottle, Takeya’s insulated bottle remains comfortable to the touch.

For those worried about reusing old bottles, each insulated water bottle is BPA-free. This ensures that, unlike standard plastic bottles, Takeya’s bottles won’t leach any chemicals after continued usage.

Takeya has also designed the bottle to be adaptable. Those who own multiple sizes of the bottle won’t have to worry about matching a bunch of different-size lids. The universal spout lid fits all five bottles. from 14 ounces to 40 ounces. Without a lid, bottles feature a wide mouth opening that allows users to easily clean the bottle or fill it with ice. Even with the wide mouth, the leak-proof locking lid will make sure that even a single drop is not wasted.

The stainless steel design comes in black, steel, white, orchid pink, or ocean blue. Buy Now  at $20 for the smallest size and top out at $35 for the largest. Every bottle purchased comes with a lifetime warranty. If customers find an issue, the bottle can be easily replaced at no extra charge.
