Filter Adapter (AOFS+)

The anti-roll design is a small touch that makes a big difference when I set it down on a slanted surface at night. Color accuracy on the maps is noticeably better, and it’s sturdy enough to toss in a pack without worry.

Reading maps at night used to mean fumbling with a bright white light that wrecked my night vision. Slapped this red filter on and it’s a total game-changer for tracking my route on the trail. The colored lens is noticeably better for keeping my eyes adapted, and the fit is solid enough that I don't

Bought this mainly for reading maps at night, and the colored filter really cuts down the glare without killing the light output. The adapter fits snugly and the anti-roll shape keeps it from sliding off the table, which is more useful than I expected. Only gripe is it took a bit of fiddling to snap
