JANA H The size is 19" x 6". We bought it for backpacking and we are satisfied. Had a rain at the holiday twice and never got wet inside. Perfect. Only the space inside is very limited. Just for backpacking and 2 average-size people.

MATT K The packed up unit is @ 8" in diameter and about 24" long.
