Answer:
Sweaters, Coats, and Shoes.
They could have a cooling system of some kind. Sometimes you might wear a sweater out of comfort possibly or because it was cold before, but now you're hot possibly. If you get a cooling system with it, you wouldn't get as hot, if you get hot at all. Same with coats. With shoes, sometimes they can trap all the heat in them at your feet, which can make them smell or uncomfortable. Your feet may also swell or something like it in shoes when you wear them for a while, which may make your feet feel hotter or something. A cooling system in them, however, could help both these problems possibly.
