LICHIFIT Dust Cover Breathable Bag Waterproof Case Heat Dissipation Mask for Tamiya TT-02 RC Model Car

Only niggle on it is that one side of the TT02 is slightly longer due to the bump on the side of the chassis, so there is a slight amount of extra material on the other side, which is fairly trivial to deal with

So much better near grass and pine needles. 95% effective offroad.
