I have been using the Big Sky Bistro French Press/Travel Mug with great luck for over a year. It is very easy to use: pour coffee, pour hot water, press and drink.

I have also taken a metal cup, heated water, poked my neckerchief in the water, added coffee and pulled out the neckerchief and drank the coffee. It was surprisingly good. Cleaning off the neckerchief is a little messy.
