The PKG Union recycled packing cubes (3-pack) are used to neatly pack and compress clothing to maximize space savings. PKG packing cubes are designed modularly with our backpacks and overnight bags. Made from weather-resistant, recycled 600D polyester outer fabric and a recycled 210D satin polyester inner fabric. All your gear is well protected and water-resistant pressure rated up to 3500mm. The Union packing cubes use 34 post-consumer recycled water bottles that make up the yarn for the interior and exterior fabric. Pack intelligently with the PKG compression packing cubes.
