Gyakusou is Nike Running's collaboration with Jun Takahashi of Undercover, named for the Japanese word for running a course in reverse. Details from the Spring/Summer 2011 jacket: a lightweight ripstop shell in white, grey and red, with a large perforated mesh panel across the back and shoulders for ventilation, bonded and taped seams, a stowable hood, and reflective Gyakusou branding at the shoulder. The vent openings are backed with mesh; the hem and cuffs are elasticated ripstop.
