This kit includes all the materials and hardware required for any of the options in the Wedge-shaped under-seat pack posted under the "projects" tag on the "news" page. This basic saddlebag sits under your saddle and holds your spare tubes, tools, tire levers, etc.
The kit includes two different colors of sturdy, waterproof vinyl-coated polyester in pieces large enough to let you enlarge the pattern a bit if desired, 12" of 1" webbing and 3" of hook-and-loop fastener, 27" of 3/4" webbing and a side-release buckle, 12" of zipper tape, and two zipper sliders. The pattern calls for binding the edges with strips cut from used inner tubes, so binding material isn't included because you can presumably find old tubes easily.
Although the vinyl is heavy, this pattern doesn't require sewing over multiple seams, so a typical home sewing machine should be able to handle it with a little care. The project is small enough that hand sewing won't take too long, although you may need pliers or a good thimble to get the needle through the material.
Note: If there's a combination of colors you'd like that you don't see, just ask! :)
