Iron Flask’s Narrow Mouth Water Bottle

Our commitment to developing sustainable products with functional features means we've considered every detail to ensure our bottles provide both ease and convenience in your day-to-day. The standard narrow water bottle from Iron Flask features a sleek body made with premium stainless steel which never rusts and doesn't leave a metallic taste in your mouth. The double-walled vacuum insulation also helps keep beverages icy cold for up to 24 hours and hot beverages will maintain their temperature for up to 12 hours. Another benefit of the double-walled vacuum exterior of the insulated narrow mouth water bottle is that it never sweats — giving you a secure, slip-free grip when you're on the move.
