This inexpensive umbrella, when deflated, would be smaller and lighter than a conventional umbrella. Made of beach ball type plastic, the upper surface would be one ply areas extending between tubular "ribs" similar to the shaft/handle.

which bits are you inflating? a bit worried that its so light it would blow away in a mild breeze.

Toss a pump (or better yet, a replaceable, regulated CO2 cartidge) into the handle.
