The Boss Triple Insulated Growler is Eco Vessel's big boy for keeping a lot of water cold for 36 hours or tea hot for eight hours. Eco Vessel included a large stainless steel infuser for loose tea leaves, red or white wine, slices of oranges, limes, pineapple, or sangria. The sky's the limit when it comes to concoctions and the Boss Growler. The dual-use leak-proof top features a wide opening for easy filling and a small opening for easy drinking, and you can exchange it with Eco Vessel's flip spout lid (sold separately).

Love this growler! The two different openings make it versatile. Easy to carry thanks to the high quality carrying strap. The infuser is a unique feature that can help you create many different types of beverages. I recommend a nice wheat beer that you can garnish with an orange in the infuser. Love it!

Beer cold-Coffee hot

  • Familiarity: I've used it several times

Extremely versatile growler. Keeps beer cold for a ridiculous amount of time, under normal conditions that is, haven't gotten a chance to take her out on the river yet in the hot desert heat in the middle of summer. Also keeps your coffee warm, I'd estimate around 8 hours or so, stays blistering hot in there for at least an hour, be careful.

Two great features about this growler that I haven't seen on any others... There is a removable coffee/tea infuser for grounds or loose leaf tea. I've used it for making coffee which it worked really well for, chewed up a few grounds but that is to be expected. My favorite thing about this growler is that it has two different sized openings; wide mouth for filling it up and a narrow mouth opening for drinking ease. If you need any other info on this growler or anything else for that matter, please hit me up directly...

What is the weight of this empty and what material is the cap made from?

So, I'm addicted to flavor in my drinks. Water is typically so boring, unless I'm seriously parched. Now that I have this amazing container that not only keeps my drinks at the right temp, but also infuses it with natural flavors, my water consumption has sky rocketed. I take it everywhere, including work.
<br />The container keeps everything cool, even in the desert. I don't have exact holding times for the temperature, but it sat in the hot sun for at least 3 hours, and it was still chill. <br /><br /> I did also put loose, hot tea in there that stayed hot for over and hour and a half. It didn't stand a chance to last much longer than that, before I drank it all. It doesn't matter how many growlers of tea you put in front of me. I will quickly drink it all. <br /><br /><br /><br />Feel free to contact me directly, with any Backcountry questions. Emily Jenson<br />Expert Gearhead<br />801.746.7587<br />
