- Brand: PORTER - Model: Union Purchased new from an authorized retailer and only used a few times, so there are no noticeable stains or deterioration. (Please refer to the photos as this is based on my personal assessment.) I think it has a large capacity and is very easy to use. The following is an introduction from the manufacturer's website: The "UNION" series is a backpack series characterized by its functional exterior pockets and distinctive form, inspired by workwear and tool pouches. The main material is polyester canvas fabric, which is lighter than cotton and less prone to fading. The distinctive front pockets, inspired by workwear and tool pouches, feature rivet details and an eye-catching green name tag (navy has the same color as the main body). Models other than the flap backpack (08692) are equipped with two long handles for easy carrying, and are designed to be highly functional and durable for hard use. The product will be packed compactly for shipping. Thank you.
