Shipping will be as small as possible. The Sub Nero is a smaller and slimmer version of the Nero Ultra backpack. It has a design that focuses on the minimum necessary functions. The Ultra fabric used is laminated with ultra-high molecular weight polyethylene (UHMWPE). It boasts extremely high abrasion resistance and tear strength, and all seams are seam-sealed for high water resistance. The roll-top closure prevents water from entering and makes it easy to adjust the space when the load is reduced. The large, stretchy mesh center pocket makes it easy to see the items inside and allows for quick access. Also, because it is a mesh material, it is suitable for drying damp clothes. Tall gear such as trekking poles and umbrellas can be stored in the side pockets. The size is also large, and the size is adjusted to fit 1-liter or 1.5-liter bottles. It is tilted forward for easy access without unloading your luggage. The back pad comes with a 28 cm x 39.4 cm closed-cell pad. The pad is secured to the main body with a shock cord and can be quickly removed during breaks.
