Stainless Steel Water Bottles

Made with high-grade stainless steel, the insulated water bottle from Iron Flask is designed to keep your coffee piping hot when you're on the go or your water icy cold in warm weather. Perfect for any kind of climate, our flask water bottle will keep your liquids warm for up to 12 hours and cold for up to 24 hours.

Our wide mouth water bottle selection also includes three different lids at no extra cost, giving you the convenience of choosing the best features for your day-to-day needs. The straw lid provides easy, drip-free access to cold water or your favorite sports drink during your workout. The stainless steel water bottle also includes a spout lid with a screw-on top, which provides reliability with a 100% leak-proof design. And finally, the flip lid option features a durable, slip-free handle that makes it easy to carry when you're on the move.

Our wide mouth water bottle is carefully designed to accommodate your everyday lifestyle, including a cup holder-friendly design in a range of sizes: 14 oz, 18 oz, and 22 oz. If you need a bigger water bottle, we also feature larger sizes, including 32 oz, 40 oz, and 64 oz. Additionally, you can also choose from a selection of fun and eye-catching colors such as Bubble Gum, Aquamarine, Fire, Kiwi Green, Midnight Black, and more. The Iron Flask water bottle also features a powder-coated finish, giving it a sleek look that holds up to everyday wear and tear.

At Iron Flask, we also feature the popular retro water bottle, which has a sleek, cola shape that fits into most cup holders found in cars, bicycles, and backpacks. Choose from a selection of elegant colors such as Bubble Gum, Day & Night, Sky, Dark Rainbow, Twilight Blue, and more. Depending on your needs, you can also choose from several sizes, including 12 oz and 17 oz (both cup-holder friendly), and 25 oz. As an added bonus, our retro water bottle also comes with a special bottle cleaning brush, which makes it easy to keep squeaky clean and sanitized.
