A lightweight and breathable backpack made of polyester material, perfect for cycling. Also suitable for running, hiking, etc. - Brand: INOXTO - Model: 577 - Size: 38x20x10cm - Material: Polyester/Net - Weight: Approximately 300g - Capacity: 12L Thank you for viewing. Although it says 12L, I think the actual capacity is less than half. Color: black. This is an offer for the bag only. I purchased it about a year ago, but I haven't had a chance to use it, so I'm selling it. I have stored it in the bag it was sent in.
