Help is required for our pony re rugs 
It has been suggested that now is the time for us to get our winter rugs but would appreciate a little advice anyway re rugs as I am confused.
Our pony didn't come with any tack or rugs so have spent a small fortune recently!
In the rug department I have his fly rug and a lightweight rug, that's it so far. I am confused by it all to be honest. Do I need a travel rug specifically, obviously it's so hot at the moment he travels with boots and tail guard but that's it. A stable rug and a heavy weight rug? One for autumn/spring or is that the lightweight one? How heavy does the winter rug need to be and does it need a neck? He's quite fine in build, although has put on weight obviously over the summer months (welsh cross with a riding pony). Previous owners didn't fuss him or double rug him, 'he's tougher than he looks' I remember her saying!
He's obviously out all the time at the moment but will be stabled in the autumn and winter.
Help greatly appreciated!
