Review on Topeak TC2260B Wedge Strap Mount by Alberto Brewster

Good size and holds everything you need (spare tube, mini pump, tire mounting lever, mini tool, tire case, patch kit, brake spacer blocks). Reviewers have complained that the seatpost strap needs major improvement, it doesn't work at all on smaller diameter seatposts. There is very little velcro left on a seatpost like this and you just have to be smart to find a way to maximize velcro contact. Also, the zipper pulls out at the bottom, which is annoying (to me). It even appears on your own product image. Not very aero in that sense :D but it's called the aero wedge package.
