Cons: Must pour carefully for bold flavor, delicate clips
Bottom line: A great ultralight backpacking option, as long as you pour carefully.
Weight: 1.1 oz
Materials: Nylon filter
Manufacturer: GSI Outdoors
The GSI Outdoors Ultralight Java Drip is the most compact camping coffee option we tested and is tied for lightest with the Primula. It's the only option that easily folds under a fuel canister. We prefer the Primula because it's easier to use and clean. It's also easier to get a consistent bold flavor. That said, the GSI has the advantage of not requiring you to lift it out to avoid steeping and may be the best option for some.

Our Analysis and Test Results
This is a nylon filter supported by three light plastic legs. The clips are a little delicate and you need to be careful to avoid the filter spilling.
This filter can produce great taste, but it requires a careful and slow pour. Add water too fast, and the coffee is weak. When we used a gooseneck kettle, it was easy to offer a precise pour. But out of a JetBoil, it was much harder.
Ease of Use
This filter is relatively easy to use but like all filterless cones, it requires a bit of cleaning after each use. It takes more cleaning than the Primula because there is more surface area. You also have the right cup to make sure the legs attach securely. If the rim of the cup is too thick, it's hard to attach the legs. Or if they do attach, they are not as stable when you pour a lot of water in.
At 1.1 oz, this is tied with the Primula as the lightest filter in our tests. That said, we ended up using more coffee to get the same taste as the Primula, which bumps the weight on a backpacking trip just a little.
This by far the most portable filter in our tests. Once you fold in the legs, the filter is small enough to fit under any fuel canister. The legs are a little delicate, so you have to be extra careful with packing it.
This scored OK for group cooking. If we had a secure attachment, you could load up the filter with coffee and pour enough for 2-3 people. However, if the mug or carafe did not securely attach to the filter, it tipped over. Overall, this is best for 1-2 cups at a time. It also takes a little time to attach and detach to cups between uses.
