Durable, waterproof and easily stored.
We bought this as an alternate to a hard shell cargo carrier because we wanted something that we could store more easily. Although it looks a little lumpy on the top of the roof rack, it held up well on a 2000 mile summer trip through the western US and up into Canada. Absolutely waterproof and held up to some very strong winds. Not as secure as a hard shell carrier but We had no attempted thefts.
