Think critically

How can the principles of air management for thermal resistance in clothing be applied to non-apparel design contexts, such as building insulation or electronic device cooling?

05

Design Principles

"Thermal resistance of apparel is a function of material properties and the management of air within the garment's microclimate."

Understanding how air is managed within clothing is crucial for designing garments that provide optimal thermal comfort. This knowledge allows designers to create more effective apparel for various environmental conditions and activities.

06

What This Means for Your Design

How you design clothes affects how warm or cool you feel because it changes how air is trapped or let out.
