The founder of Outin is an avid outdoor hiking enthusiast who always had a challenge enjoying a cup of coffee in the mountains. Regardless of the method, he would have to carry a bunch of equipment to make a decent cup of coffee. After countless experiments and improvements, he invented the Nano portable espresso machine for coffee lovers. Outln's Nano is a perfect holiday gift for the coffee lover on the go -- a portable coffee maker that can heat water, be lightweight, and produce high-quality espresso within minutes.
