Vacuum Flask

The 22oz is 2.9 inches wide at the base; 9.4 inches tall; weighs 11oz; keeps drinks cold for 24 hours and hot for 12 hours; and fits most cupholders.

The 32oz is 3.5 inches wide at the base; 9 inches tall; weighs 13.2oz; keeps drinks cold for 28 hours and hot for 12 hours; and does not fit most cupholders.

Made from stainless steel with double-walled and vacuum-sealed insulation, this durable wide-mouth bottle keeps your drink at its optimum temperature for hours. And, its exterior never sweats. So say goodbye to coasters and slippery bottles!

Plus, it's got a variety of lids to choose from! Each Keto Chow Stainless Steel Vacuum Insulated Flask comes with a BPA-free plastic Flip Lid with a handle (ideal for hot liquids), you also receive either: a stainless steel twist-on lid, or a flip-up straw lid (see the photo for which one comes with the different colors).

The Keto Chow Stainless Steel Vacuum Insulated Flask is hand wash only. Manufactured by Simple Modern.

Designed With You In Mind

If you've been reading our blog for very long, you'll probably know that we've been advocating vacuum insulated flasks for years and now they're available with a super cool Keto Chow logo laser etched on one side. Perfect for when you're:

  • Staying Keto at a conference.
  • Running around a weird city (sorry San Francisco, you know it's true =).  
  • Stuck in a class all day and you know the lunch options are going to completely suck.  
  • Driving around.  
  • Hiking
  • Running around Disneyland (though those smoked turkey legs are pretty awesome).

How To Use

You need to either pre-refrigerate your Keto Chow for several hours or add in some ice cubes - in our experience, the insulated flasks will keep Keto Chow cold for at least 18 hours but the liquid needs to already be cold! The double-wall vacuum insulation keeps hot drinks hot up to 12 hours and iced drinks cold up to 24 hours. The stainless steel won't transfer flavors or odors to your next drink. This means your favorite beverage is always pure and refreshing.

The flip-top lid should keep your gear nice and clean but please do make sure that you close the lid before you put it in your backpack.

Love the Flask

Great flask

high quality and well made, comes with a straw lid, 2 straws and a sipping lid. We're using it as a water flask instead of putting Chow in it since its easier to clean our blender bottles, but I'm sure it works well with Chow in it, too.

Super Awesome Insulated Flasks

I got my first insulated flask a while ago (on left) and liked it so much, I ordered a second one (on right) so I can be sure to have one to take with me as it gets hotter here in Texas ! Thanks for making such colorful bottles !!

Very happy

I make my lunchtime shake in the morning before leaving for work, and the vacuum flask keeps my shake warm or cold depending on the beverage type (usually 4-5 hours). I haven't tried it beyond that timeframe, but I'm happy with it. Also, I love the fun designs/colors.

Awesome products!

Very high quality, attractive, durable, and so convenient to use at work to keep the soups hot and shakes cold. You can even pop a shaker ball in it to use instead of a shaker bottle or blender and save a little more cleaning up! Love it!
