IF YOUR VERSION OF OFF-ROADING IS AT THE COMPETITIVE END, especially the kind that involves speed, you won’t need any telling that safety kit is right at the top of your list. A good cage, good brakes, the best helmet you can afford and, of course, harnesses that’ll hold you...
Being soaked through for a prolonged amount of time is part and parcel of off-roading, particularly if you a) do it competitively or b) drive a Land Rover that leaks. Or both, obviously.
