See Top Ranked Backpacking Water FiltersKatadyn Gravity Camp vs MSR Trail Base
See our analysisAnalysis:
The Katadyn Gravity Camp 6L hasn't managed to get enough recognition from sources that do high-quality hands-on testing and therefore didn't make it into any relevant roundups. That, by itself, makes it difficult to recommend.
As for the MSR Trail Base 4L - OutdoorGearLab, a source that conducts reliable hands-on testing, has featured it in its The 7 Best Backpacking Water Filters of 2023 roundup. However, it didn't make it to any of the top spots.
