The GSI Outdoors Ultralight Java Drip was the most compact camping coffee option we tested. It also tied with the almost as tiny Primula Single Serve Coffee Brew Buddy as the lightest. We preferred the Primula, our Top Pick for Backpacking, because it was easier to use and clean, but liked that the GSI sits above your vessel while brewing instead requiring you to lift it out of the cup to avoid steeping.
While we found the flavor from the Ultralight Java Drip to be just fine, our two Editors' Choices fared better. Check out the Hario V60 for a filtered version and the Cafellissimo Paperless Pour Over for a non-plastic filter-free option.
