Nicer looking than an EKG pocket guide, this heartbeat travel bottle is both functional and aesthetic. Fill it with ice cold water and take it to the gym for your cardio workout, or top it off with coffee for a long night shift in the cardiac ward.

With a textured design for a unique tactile experience, this flask will keep your drink hot or cold until you're ready to enjoy it.

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!

Perfect gift for an RN

This was a gift for my husband who is a PACU/SACU/OR nurse. He loves it and uses it to keep coffee warm during his shift, works great and he’s gotten many compliments already!

Great quality

This was a perfect graduation gift for my 2 classmates that are going into cardiac & ICU nursing! Everyone that saw it asked me where I got it! This bottle is super high quality & so unique! (Plus it's actually useful if you need a quick glance at the information to refresh your memory!)

Great Gift

I bought this for my friend who is an EMT. He just got a new job at a bigger and more prestigious fire department and I found this for a congratulations gift. I wasn’t sure he’d like it, but he loved it and had to take it to work to show it off to some friends. I have won gift giving this time. Does need to be hand washed.

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.
