Always cold or always warm

I have a black Hydro Flask and every summer day I will fill it with cold water and leave it out on the boat or dock all day - the heat will make the water bottle hot - but because of the air insulation the water stays just as cold as when I filled it up 10 hours earlier. In the winter I fill it with coffee and it stays warm all day! Best water bottle on the market!!!
