Yeah, it shows the old gear is about two kilograms heavier than the new gear, which is huge.

Considering that someone carrying 2 extra kilos will also be generating more body heat etc, the focus on heat over the rest of the article is in question.

To clarify slightly: it shows the old gear is significantly heavier in three areas: head, hands, and ‘accessories’. I think that suggests where investment in technical fabric has been most successful at improving the burden of mass in surviving extreme cold.

Wool, down, silk and leather are still commonly used in technical apparel and compete on weight.

2 big new innovations that matter are Gore-tex and Nylon fabrics that are very durable and wind resistance for their weight.

		Tech fabrics were a prerequisite to the widespread use of down in adventure clothing. Earlier fabrics were either too heavy, like leather, and would collapse the down and negate its insulating properties, or would get wet like cotton/linen and saturate the down.
