Newtro Fashion The GAP collection plays up the retro vibes through an incomplete typeface logo with contrasting color pairings. The novelty of the bag can be found through the anti-scratch and water-resistant PVC polyester, a modern fabric popularly used in outdoor equipment today. The retro modernism is put in contrast through the collection’s design and material selection, allowing the bags to fall into a “newtro” category of its own.
