My Dartmoor has rainscald, he lives out and has shelter but chooses not to use it! I need to rug him (he has a temproary one on at the moment but it is too thick). Just wondered what you thought was the best lightest turnout rug, and affordable! I literally just need something to prevent the rain hitting his back! As little warmth as possible as he is supposed to be a hardy pony that can live on the moors
