Water Bottles

Retro Bottles

Our vintage-inspired retro water bottles have a sleek, classic shape you’ll love and a familiar cola-style drinking pace, thanks to their small opening. 

About Iron Flask
At Iron Flask, we’re consumed by quality and obsessed with aesthetics. We design our water bottles with premium stainless steel, double-wall vacuum insulation, a range of features and sizes, and collection-worthy colors and patterns.
Stainless Steel Water Bottles
We craft our retro water bottles from 18/8-grade stainless steel. Why does that matter? Because this high-quality food-grade steel won’t rust and won’t transfer weird flavors to your beverage. It also won’t get tossed in the trash—these stainless steel bottles are built to last a lifetime. And they come with a leak-proof stainless steel screw-on cap and a retro-specific cleaning brush to keep them clean as a whistle.
Vacuum-Insulated Water Bottles
When you’ve just wrapped up a long hike in the hot sun, the last thing you want is a swig of warm water. And a room-temp cider just doesn’t hit the spot during a frosty winter walk. Iron Flask water bottles’ double-wall vacuum insulation keeps cold drinks cold for up to 24 hours and hot ones hot for up to 12 hours.
Retro Water Bottle Sizes
The 12 and 17 oz retro water bottle sizes fit nicely in almost any cup holder, while the 25 oz size offers more volume and will fit in some car and backpack cupholders. (Double check the measurements to be sure about your setup.)
Water Bottle Warranty
At Iron Flask, we stand behind the quality of our water bottles. We offer our customers a lifetime warranty against manufacturing defects and a 100% satisfaction guarantee on all of our products. Reduce plastic waste. Hydrate yourself. Stay looking fresh.
