**SOLD and shipped!**
Not ultralight, but I thought I would offer this to the crowd here before taking other avenues. Great urban/bike backpack.
Chrome messenger style backpack, black nylon with red tarpaulin interior and Google logo embroidered on the top flap. Closest to the current Romer model (http://www.chromebagsstore.com/bags/packs/romer.html), but it does not have pockets on the outer ends. 2lbs7oz on my scale. In excellent condition, basically new without tags. There are two faint dark lines on the red part of the flap (very subtle). $50 including shipping to US addresses and PayPal fees.
