I put medium weight on when its still chilly during the day. Atm were still having warmish days so he'll stay in his light weight. I think by next weekend he'll be in the medium weight.
My TB's out at night and his field is quite exposed and windy. Can't believe that 2 days ago it was warm and he went out naked, last night he had a rain sheet and tonight he's in his landa mediumweight with a neck.
He has nothing in the day in his stable though.
