The Jetboil Silicone Coffee Press is a simple way to get coffee in the backcountry. Designed to work with the Jetboil Flash, MicroMo and Zip, plus 1L tall and .8L spare cups. Boil water, add coffee, cover with press and lid. When it's time, press down the plunger and the silicone ring smoothly slides down the cup and presses your coffee so you can drink in the delicious brew. Doubles as a steamer if you flip it over and you can get some fish or veggies going. Probs wash it real good after that.
