One thing this 1977 field manual drives home is how much real improvement there’s been in clothing and basic goods in the last few decades

Like it’s a picture of a world where clothing is a lot more precious AND less functional, more limited in range of usable conditions so that meeting even minor climate variations requires extensive layering and accessorizing

A world where you will have to mend and thoroughly clean it regularly, by particular procedures according to fabric type and treatment, and exhibit particular skill at wearing it, and if you do these things wrong you will permanently damage or destroy an expensive object or literally set yourself on fire
