I recently improvised this pour over solution while traveling and it's so simple, light, delicious, compostable and cheap, I've been taking it camping.
Bring paper filters and ground coffee, and use a fork, spork or cut a forked twig (which works even better) to keep the filter from collapsing into the cup.
Here I doubled the paper filter to make it stronger, but I've had success with a single filter too (be gentle). You could get all fancy by stringingstring it above the cup somehow. You so you don't need anything fancyhave to make totally great coffee!hold it up and wait at the end of the pour.
Next level on quality: use a hand grinder to grind whole beans just before brewing.
Third level: if you'll be out more than a couple weeks, roast green beans in a dry frying pan or pot.
