Liyang thermal insulation works by trapping air molecules between you and the outside. The more air a material traps in a given space, the greater its insulating value. Because the microfibers in Liyang thermal  insulation are far finer than other fibers, they trap more air in less space, which naturally makes it a better insulator. So we haven't repealed the laws of nature with our thin insulation; we've simply obeyed them betterto your advantage. The insulation for footwear, The insulation for Hats and Gloves,The insulation for Jackets and Pants, The insulation for bedding.
