For thousands of years, mankind has carried water and sought better means to carry water. Over time, we’ve seen water-carrying technology go from sewn animal skins to metal canteens to plastic bottles to hydration packs – each with their positive and negative features. Indeed, the basic water bottle, a means of carrying enough water to slake thirst while between running water sources, has seen its share of design ideas and features: you can find a water bottle of virtually every size, shape, and color. Moreover, water bottles have sported a variety of means to get that water into your mouth: pour, squeeze, straw, flip top, and so on.

Sometimes, however, we outdoorsy people want a more durable means to carry water and occasionally carry something other than cold water or a sports drink – maybe hot water, coffee, tea, or soup. The thermal demands of hot and cold fluids coupled with a desire for minimal size and weight pushed water bottle manufacturers to again reconsider water bottle design. Combining new and old-school materials with unique design features, Hydro Flask offers a strong lineup of the latest in water bottle technology, including a 21 oz Standard Mouth Vacuum Insulated Stainless Steel Water Bottle. It keeps hot fluids hot, cold fluids cold, all in a very durable steel container.

    We are very happy with our 40oz Hydro Flaske bottles!!! Not only is it a great product but they offer wonderful customer service. I dropped 2 bottles head 1st onto concrete which cracked the lid(s) and would allow leakage to occur if the bottle was tilted or turned upside down. The Hydro Flaske company sent me 2 new lids without any questions or costs not even shipping! My only complaint is that it keeps my beverage too cold when I add too much ice! lol
    I will never buy another brand of water bottle again! Thank you Hydro Flaske!
