The best backcountry coffee filter I have ever used. don't buy anything else, just buy this. works best with a slightly coarse grind. think new yorker.

Convenient and enviro-friendly, this reusable coffee/tea filter lets you brew up a cup without wasteful and messy paper filters. It’s low profile enough to be stored in just about any mug or cup and it weighs just .98 oz./28 g.
