I got some of those knee board type things from Lidl, sold as flat pieces of moulded plastic you kneel on but I use them as fenders. They are flat so stack into a small space, best thing was they were only 2e each so if get nicked, lost or grubby IŽll just chuck them. They are a bit light so I put some metal strips (edges rubbed off) in the bottom air chamber.
Also, yesterday I bought some wet suit shoes from Aldi, a whopping 4.5e.
Lidl & Aldi stuff is tops, donŽt clean it just chuck it & buy new every season.
