I've accumulated a variety of Patagonia bags for work and travel. I've found them functionally designed and very durable. My favorites are the large wheelie (top left) and the Maximum Legal Carry (middle right). The MLC wheelie is perfect for camera gear (top right). A couple of these bags were replaced (no charge) by Patagonia (a wheel was smashed on the large wheelie and the interior surface of the MLC was damaged)--they have a great guarantee!
