Mesh Pocket Add-on for chant! - Brand: chant! - Material: Mesh - Color: Black Thank you for viewing. Although I have discarded the tags, this item is unused. I am selling it because it doesn't fit my existing backpack. The following is from the manufacturer's website: Official Website: Can be attached to alpine backpacks and backcountry backpacks that do not have external pockets. As an attack pack: Can be carried like a daypack on its own. Useful for carrying luggage at the campsite or as an attack pack to the summit. Folding poles and pads can be attached using the loops at the four corners. As a helmet holder: Can also be used as a helmet holder with a pocket. * May not fit depending on the size of the helmet. The mesh itself has almost no elasticity. Accessory hook: You can attach keys, headlamps, multi-tools, etc. that you want to take out immediately to the accessory hook at the entrance. The fabric uses lightweight and durable XPAC. The mesh fabric uses a woven 210-denier semi-dull nylon with excellent strength. It has moderate firmness and stiffness and little stretch, which reduces the shaking of the luggage. Capacity: 8L Weight: Approximately 90g
