I’ve finally got a glimpse at the rumored Nike LunarSwift+ Breathe it would appear, courtesy of chajinyoung.com. Initially there are two colorways, white/orange and white/purple-volt, withe the primary point of difference between the standard LunarSwift+ and the Breathe being that the latter features a perforated pattern on the side panel between the overlays.
