Would love some advice on a liner for a waterproof turnout for my 13yr. Old quarterhorse.
He will be outdoors during the day/night when the temperature drops into the 20's and I am going to purchase a 200 or 300 gram liner to go underneath his unlined waterproof sheet.
He DOES have a natural furry winter coat and I want him to be warm but not over-dressed.
Please advise: 200 gram or 300 gram?
