Fleece and Thinsulate-like Fleece
These materials provide insulation through the creation of a thin layer of air pockets within their structure.
This works because of the principle of thermal resistivity: as heat must travel through an area with more resistance than before, the heat dissipates slower due to a higher barrier (this is the concept used by insulators) and, subsequently keeps more heat with the insulated area. -
Down-filled Insulation
Down-filled insulation utilizes the natural insulating properties of animal down (usually from geese and ducks) to provide warmth, trapping warm air close to the body and keeping it in using a layer of insulating material.
-
Synthetic Insulation (PU and Polyester)
Synthetic insulation, such as PU and Polyester fill materials, mimics natural down’s insulating capabilities. This synthetic insulation option does not lose thermal efficiency even when wet, and is usually less expensive and less eco-impact compared to down-filled options.
-
Hybrid Insulation
Hybrid insulation combines multiple materials to achieve superior warmth and lightweight features, such as down-filled combined with synthetic insulation.
Advancements in Materials Research
