Well, we wear sweaters in the extreme cold, but have you ever felt in the harsh winter, Ish! If the sweater was light instead of heavy, it could create a hot atmosphere like a heavy sweater at the same time! In countries where snow falls, such a desire is more among the people of those countries, because everyone has to wear a very heavy downcoated sweater in the extreme winter! But
In fact, even though it is a light sweater, such a cold control system is very rare, but recently a group of researchers at Xinjiang University has made it possible!

And, this sweater has been used, Aerogel Coated Fiber! A previous study by Weiwei Gao and his colleagues detailed that this thin yet insulating material matches the warmth of a down jacket despite being one-fifth thick! Not only that, sweaters imitate a technique inspired by frizz-spinning, by which they replicate the internal structure of the bear's fur, which increases the stability and flexibility of the fiber.

The advantage of this sweater is that, compared to many heavy down coated jackets, the aerogel-coated fiber maintains its thermal insulation even after stretching, washing, and dyeing. This sweater is more effective than a downcoat even in -20 degrees Celsius
