The smell-proof RAW Backpack is insane! Designed to lock in smells – even really strong danky odors – entirely! It uses a proprietary 6-layer design, a water proof foil layer, mesh layer and a final layer of naturally durable Burlap! Plus, it’s got not one but TWO silicone gasketed zippers for added security and privacy! The RAW Burlap Backpack – RAW’D Out Edition comes complete with 7 seven different RAW patches embroidered to the front and sides of the burlap exterior. 17”x12”.
