I remember years ago someone trying to find shades to fit the kitfox.
I ran across a sunshade kit at our local Costco last week manufactured by WinPlus North America (866-294-9244) PN: WIN-54645-V2. It contains three shades. The larger 34 x 64 I retired to the truck. The two smaller mesh screen fit perfectly in the Speedster. They have suction cups attached at 2 point on each screen. The cost was around $20
