Abstract: Disclosed herein are garments having any combination of low thermal conductivity, high durability and resiliency, and with the optional ability to evenly distribute compressive forces. When compared to currently used compression garments, these compression garments advantageously result in better patient comfort and overall improved healing processes. In certain aspects, the disclosed compression garments include post-surgical treatment masks. For example, the post-surgical treatment mask may include a thermoformable assembly having a thermoformable resin arranged between inner and outer knitted fabric layers, the thermoformable assembly configured to be heated to a glass transition temperature of the thermoformable resin such that the thermoformable assembly can be shaped to conform to contours of a user's face, and a styrene-based polymeric gel layer arranged on the inner knitted fabric layer.
