Chrome Welded Rucksack
Chrome Industries 

I've got a couple of friends here in LA who've ditched the grind of sitting in traffic and now commute to work by bike. But hauling a laptop and other tech accessories while pedaling can prove to be challenging on the streets of any city, requiring secure and weather-proof carrying gear. The Chrome Welded Rucksack seems up to the task: waterproof, accommodates up to a 15" laptop, U-lock pocket, and includes a removable laptop sleeve.
