This is the Race, a cyclist's backpack made by Deuter of Germany. It's an ultra-lightweight backpack with mesh even on the shoulder pads, designed specifically for cyclists. There are two minor issues: Firstly, the zipper on the top (near the H2O marking) is starting to fray slightly, but it's still functional if opened and closed carefully (see the last few photos). Secondly, while I don't think cyclists encounter rain often, it doesn't have a rain cover. I've used this model, and others like it, for about 8 years, and I only remember using a rain cover a few times. It features the Air Stripes System, which contacts the back on either side of the spine. It has mesh pockets on both sides. Manufacturer: Deuter Model: Race 10L Backpack Size: Height 42cm, Width 21cm, Thickness 16cm Capacity: Approximately 10L Weight: Approximately 560g Materials: Hexlite 100, Deuter-Ripstop 210 It not only vents heat upwards from the back for high breathability but also maintains stability against side-to-side movement. I've used this backpack since I started cycling, and it's been very useful. For trips of about two days, you might need to pack carefully, but it's compact and convenient for carrying the essentials. I used it about four times a month, but I'm selling it to declutter. I've even used it for 600km brevets occasionally. I'm selling it because I bought a new model, but it was in use until last week and is in good condition except for the two issues mentioned above.
