This is a cooler saddlebag from Jindaiji Mountain Works. I'm selling it because I no longer have the opportunity to use it. I purchased it last year at an event and have kept it stored at home without ever using it. It can be attached to bicycle saddles, frames, and backpacks. Using the included insulated Astro Cozy, it can carry two 350ml cans, making it a beer container. It can also be attached to your own backpack, making it suitable for activities like mountain climbing. Although it is a new, unused item, please understand that it has been in someone's possession before. - Design: Cow pattern - Material: Water-resistant material - Brand: JINDAI MOUNTAIN WORKS - Function: Cooler saddlebag - Straps: Adjustable straps Thank you for looking.
