What's the role of the chainmail and scale armor on InSight's WTS?

It's like taken directly from a medieval armor...

The role of wind and thermal shield (WTS) deployed over the seismometer is in its name - protecting it from noise and thermal changes. This is fairly clear - and achievable by classic means; a rigid protective shell on the outside, possibly a padding on the inside, the "bellow" skirt to align it with the uneven ground... but I just don't see where the chain mail and scale mail skirts come into the picture. Other than being rather heavy (pulling the kapton skirt to the ground) - which could be achieved by other (admittedly less cool looking) means, I don't see their role. Especially that neither was famed for being particularly good against heat, cold or wind.

How do they help in thermal and wind protection?

• What, no chainmail tag? I'll advocate for that if you advocate for a Gilligan's Island tag. – uhoh Feb 11 '19 at 11:47
• Perhaps to protect against pointy bits on the Martian surface? – Chris B. Behrens Feb 11 '19 at 15:50
• Allied with @ChrisB.Behrens comment. It might be a simple way to provide a flexible seal with the ground to minimize gaps between the ground & the protective skirt. – Fred Feb 11 '19 at 16:23
• Chainmail alone would suffice for that. Or even a spongy bottom seal. – SF. Feb 11 '19 at 16:29
• Mars is named after the roman god of war, after all. Better come prepared. – Ingolifs Feb 11 '19 at 22:12
