Any interest in classic style canvas gaiters? My wife has been doing some sewing projects for her shop, and one I've thought about for my commute is basic water resistant canvas gaiters with Scotchlite fabric trim. Since the hot weather down here makes knee-length insulated gaiters pretty much useless, we were looking at something that would come to about the bottom of the calf muscle bulge; just enough to keep the pants from working their way up and out easily. She's thinking they would be priced along the lines of $40-50.
My thinking is that I'd like something I can throw over work shoes that would keep both the pants and the shoelaces out of the chain, keep some road grime and splashes off the pants cuffs and shoes, and provide a nice large ankle reflector. Heavier canvas might also help out on trails with lots of low brush.
