Hydro Flask® began with a challenge: to create a reusable water bottle that truly performs in any environment. It had to keep hot liquids hot and cold liquids cold. It had to be BPA-free, lightweight, durable, sweat-proof, freeze-proof, recyclable, and come with an unconditional lifetime warranty. Hydro Flask® met the challenge! The Hydroflask® 18 oz Wide Mouth bottle is made from 18/8 stainless steel with patent pending double-wall vacuum insulation that ensures the temperature of the liquid inside never mingles with the temperature of the environment outside. The best part is that this is a two-way street; whether you've got hot or chilled liquids inside of your Hydro Flask®, the internal temperature won't affect the temperature of the container in your hand. That means no blistered fingers with your daily cup of coffee and no troublesome sweat rings-from your bottle of ice water. Your hots will stay hot for 12 hours, and your colds will stay cold for 24.
