Mate Green presents you with our latest invention - brand new Yerbomos 4.0. We’ve done everything to ensure that this special thermos is better and bigger than its older models. How we’ve done? Yerbomos 4.0 can store nearly 60 grams of your favorite yerba mate, it can easily keep your drink at a stable temperature for 3 hours with little to no dropdown over the course of the day in the initial 10-hour window. The lid is hermetic, meaning our thermos not only keeps warmth really well, it also doesn’t leak no matter how you choose to transport our product. So even when some unexpected commotion happens, your bad should be dry and alright. How do you use our Yerbomos 4.0? Take of the lid and put your favorite yerba mate in (25-50 grams should be enough) the upper chamber. Pour warm water (75 - 80 celsius) into the bottom compartment and you can drink. That’s right, our thermos doesn’t require you to prepare anything in advance. You can just use it like your default tool for making your favorite drink. Each time you take a swig out of this thermos, a portion of the water will automatically transfer to the upper chamber to keep your yerba mate tasteful, rich, and deep.
