In this Article Nike‘s Nike ACG sub-label recently expanded its lineup of high-tech hybrid hikers with a HAVEN-exclusive ACG Mountain Fly Low, and now the silhouette is back in its first two in-line colorways: “Fossil Stone” and “Anthracite.” Boasting a striking build and reinterpreting some of Nike Running‘s most advanced tech for the great outdoors, the ACG Mountain Fly Low is more in line with Errolson Hugh‘s futuristic take on ACG from the mid to late ’10s than the colorful, granola-esque outdoor gear that ACG produced in the ’90s. Both colorways are made from a synthetic webbed nylon that’s secured by an expansive lacing system with anchors fused to the forefoot’s taped seams. On the “Fossil Stone,” a two-tone look is used with the eponymous hue on the outside and black on the inside; on the “Anthracite” things are kept entirely tonal, save for a few pops of bright infrared. Each also offers a large ACG spellout graphic on the lateral forefoot and a traffic-sign like reflective material on the heel’s triangular logo.
