Nicer looking than an EKG pocket guide, this heartbeat travel bottle is both functional and aesthetic.

Fill it with your favorite mulled hot cider or cold brew, and even if you don't get around to drinking it for hours, you can expect to find your beverage ready and waiting for you at just the right temperature. The metal cap seals tightly, so it won't leak all over your bag. 

Here's how it works: the space between the inner and outer flask wall is evacuated, creating a vacuum (well, a partial vacuum anyway...). In order for heat transfer to take place from the outside world into your cold drink, or from your hot drink to the outside world, it needs nearby molecules to excite. If there aren't many molecules nearby, as is the case in a vacuum, the heat's energy can't easily be passed along, so your drink stays close to the temperature it was when you put it into the flask for a really long time. 

Simply stated, vacuums make great thermal insulation!

Good for your heart

I love it I just wish it was larger. 40oz would be better! All of my co workers love the flask.

Husband of the year

I bought this for my wife. She is a nurse on the cardiac floor. Yes, she saves lives everyday but she became a hero when she showed up on the floor with this dope flask! In turn, that made me a hero for buying it for her. Thank you for making me look good!!

Perfect gift

Keeps iced drinks cold and hot drinks hot. Perfect for a healthcare worker who doesn't have time to get to a cup of coffee right away.

LOVE it!

I LOVE this thing. It's amazing. Keeps things cold (haven't tried hot yet, it's not chilly enough here). All of my friends in the medical field are jealous. It's awesome.

Everyone is jealous!

I purchased this for my mother-in-law (she’s a telemetry technician) and all her work friends are so jealous! They’re buying their own soon
