A study in materials, textures, and composition, our Blackout Patchwork collection features tonal renditions of ILE shop favorites. Blackout Patchwork pieces are made using panels of four hard-wearing, weatherproof fabrics: VX21 XPAC, X50 XPAC, 500D Cordura / 275 Dyneema Ripstop, and 1050D Ballistic Nylon. To maximize functionality the fabrics appear in a gradient from heaviest at the bottom to lightest up top. A technical version of a simple panel-loader style backpack, with weather resistant zip closures, a lightweight frame sheet for structure, and built in laptop sleeve. Rugged enough for everyday commuting, but light enough for a weekend hike.
