WES Winged Eyecup/Rainguard Set (NL PURE, EL, SLC, & BTX)

These sure block out light from the sides when spending long hours glassing. The picture being viewed is brighter and the breezes won’t dry your eyes. Your eyes will thank you.

Works as expected! Cuts glare/light coming from the side. A must, at least for me, to ensure I'll stay behind the glass when the sun is coming from the side.
