Thank you for viewing. ■ Product Overview Made of high-strength stainless steel mesh (eXoMesh), it is designed to protect your luggage from theft by wrapping backpacks and duffel bags. It is especially known as a standard item among overseas travelers and backpackers to prevent pickpocketing, theft, and slashing with knives. ■ Main Features The entire bag can be wrapped in a mesh of wire and secured to a fixed object such as a pillar or bed leg with a padlock. ■ Supported Size ~70L I purchased this about 10 years ago when I did a zero-to-zero traverse from Miyanoura to Ohkawa in Yakushima. I used it to wrap my backpack with "Pacsafe" at a mountain hut and left it there, exploring the surrounding area with nothing but myself as a base.
