It will depend on the temperature and what type of clip you do.
Depends on your country's climate and temperatures. Here it's 5-8°C at night and around 15°C during the day, so the clipped horses wear a 200g rug. When it gets colder we put a 100g or 200g rug on top of it at night.
It depends on what temperatures there are at youre stable. I personally think a 200g rug isn’t enough. I would recommend a 300g rug.
