A versatile backpack with a capacity of approximately 40L, featuring an insulated pocket and a simple cooler function. - Capacity: Approximately 40L - Color: Black - Features: Insulated pocket, simple cooler function - Design: Zipper access, external pockets Thank you for viewing. I purchased this two years ago. I've replaced the zipper pull tabs on the bottom and added a homemade bungee cord to the loops on the surface. I'm planning to sell it as is, so please take a good look at the photos. Feel free to ask any questions in the comments. I don't see any noticeable stains, but please understand that this is based on my personal assessment.
