The leg warmer should be very warm, but not the thicker the warmer.
This is like money. Of course, having money will bring happiness, but it is by no means that the more money, the happier.
The thicker the leg warmer, the less elastic. The denser the fabric of the leg warmer, the more difficult it is for them to be stretched. You can easily spot this on carpets, which have almost no horizontal elasticity because they are very thick. If the leg warmer does not have good elasticity, it is difficult for them to adapt to the knees and calves at the same time. If you want to match boots, they may not be able to cover your knees and just always stay in the boot.
If leg warmers are too thick, they may add too much weight. A leg warmer of more than 300 grams is the weight that can be clearly felt. They may cause a burden on the calves. If you choose to take them to yoga or dance classes, they may upset your balance and make you feel unfree.
High-quality leg warmer should take into account warmth and flexibility. Their best thickness is like thin sweaters, warm and light. Their elasticity should take care of thick calves and even thighs at the same time, so you can stretch them easily to protect your knees.
