If you love camping, trekking, off piste skiing or generally going into the wild and away from humanity for a few days and you love coffee, this is the invention for you.

The coffee brew bag allows users to pour hot water into a heat proof bag and brew a coffee through an in built filtration system. After brewing the coffee can then be poured directly out of the same bag through a different hole.

From the video presentation It looks quick and simple to do and could go some way to solving the issue of bad tasting instant coffee when camping.

The bag is made by a company called Growers Cup and the bags come in a number of different varieties.
