These tights look like fluffy polyester socks (though not as fluffy). They were really good for keeping my daughter's feet warm during the cold winter days last year. I wouldn't recommend them for hot weather but they are great for cold weather.
Pros
Tights are made of high quality materials, which makes them very strong and durable. Withstands frequent use and washing without losing shape and color.
Cons
Tights may not be strong enough to withstand the wear and tear of daily use, which can result in tears or holes.
