Timbuk2 Sonoma Seat Pack. Paradox: when you're hitting the open road, you don't want anything weighing you down or throwing you off kilter. But the longer the trip, the more stuff you're going to need. Solution: the Sonoma Seat Pack. Compact when you don't need the space, capacious when you do: the adjustable straps keep it securely attached to any seat. Reflective strips keep you visible at sunrise and sunset, and an external side pocket offers easy access to essentials like keys and cash. Take the scenic route. Bring an extra sandwich and plenty of water for the road. Pack a change of clothes for your destination, and then forget about it until you get there. The Sonoma Seat Pack frees you up to enjoy the ride.
