The actual insulation of multilayer clothing

Found that internal radiative heat transfer in an ensemble was significant for insulation, that intrinsic clothing insulation is a useful concept only for indoor climates, and that shape plays a minor role. The literature agrees closely on insulation and clothing surface area figures, and the latter are compatible with model predictions. Finally, it was shown that wind, body motion, the effects of posture and the fit of garments are predictable. (Abstract amended)
