Our winged rubber eyecups are the ideal companion for most 1¼" Eyepieces.  The winged extension completely blocks out extraneous light from the periphery more completely and more comfortably than the typical rigid or foldable 360degree eyecups supplied with even high-end eyepieces.  It is much easier to concentrate on the image and to see faint objects, while imparting a more 'intimate' view, isolated from distracting side-light.  We find these to be outstanding for binoviewing.  The winged extension folds down for more compact storage.
