MARPAT is the shortened name for "Marine pattern." This pattern is a multi-scale camouflage pattern is formed using small rectangular pixels of color, typically with various browns and greens. The MARPAT pattern has proven itself as a very effective camouflage versus standard camo patterns since it mimics the dappled textures and rough boundaries found in natural settings. MARPAT is also known as "digital pattern" or "digi-camo." We carry 1.1 oz. poly ripstop, Silpoly PU4000, and calendered poly ripstop. These are perfect for applications such as lightweight hammocks, gear sacks, light duty packs, and even lining material.
