Yakima DryTop

At just 3 lbs and 16 cu ft, the DryTop is one of the lightest rooftop bags available. Welded seams provide real waterproofing, and it works with or without a rack. Here's the thing: for occasional use, a 3 lb bag that folds into a closet beats a 50 lb hard box that needs garage storage. The downside? Zero security, soft sides mean more wind noise, and loading shape is unpredictable.
