I am selling this item because I have no opportunity to use it. The material is made of X-PAC, a durable, abrasion-resistant, and waterproof material. X-Pac is a laminated fabric composed of layers of nylon, polyester, and PET film. This material is specially designed to be as lightweight as possible while increasing abrasion resistance, offering excellent flexibility, lightness, and waterproofness. It has a simple roll-top construction, allowing for quick loading and easy volume adjustment. Despite being a small pack, the harness is sturdy, providing a comfortable carrying experience. Specifications: 14L Height 52cm (back 38cm) Width 25cm Depth 9cm Material: X-Pac YKK Aquaguard zipper Weight: Approximately 200 grams This is a used item, so please refrain from purchasing if you are sensitive to such matters. Also, I will ship it in as compact a size as possible. Please be aware that there may be creases as a result. Thank you for viewing.
