Modern horse rugs most often have a fibre sheet fill. This has structure like a duvet (lots of air and a few fibres) so packs down over time, reducing its insulating qualities a little. Because it's stitched into the rug you can rarely fluff it up like you can with a duvet, but tumble drying after laundering sometimes works. Forget it with a turnout, though - the outer's usually too inflexible for this to work. So basically a five-year-old rug won't be as warm as when it was new.
Unfortunately modern rugs don't last forever, which the old-fashioned sort often could. There wasn't much to go wrong with jute stable rugs - you just added wool blankets underneath as the weather got colder. And we all used to do pretty well with blanket-lined canvas turnouts before ripstop and ballistic nylons.
Modern materials are a lot lighter and more thermally efficient, but you pay for that with reduced lifespans. Lightweight turnouts are my particular pet hate - unless they have at least some padding the movement of the lining wears the waterproof coating off the outer so they rarely last more than a couple of years before leaking
Hope that all makes sense
