Iron Flask Wide Mouth 64 oz Water Bottle vs GEDUX 64 oz Insulated Water Bottle

Both are 64 oz double-wall vacuum bottles that hold cold for about 24 hours and hot for about 12. The Iron Flask gives you three interchangeable lids and a well-known brand with broad accessory support; the GEDUX gives you a 2-in-1 straw/chug lid, spare straws and a cleaning brush in the box. Build is comparable 18/8 stainless with a powder coat, so pick on lid flexibility versus included extras.

• Choose the Iron Flask if you want swappable lids for different uses and a brand with a long track record and easy-to-find replacement parts.
• Choose the GEDUX if you want a single lid that switches between straw and chug, plus spare straws and a brush included.
