Time was when you couldn't get your kids into those useful winter items, vests. They'd go to school freezing rather then wear such a duff item of kit. I believe a lot of shops no longer do the stringies.
They cost a lot more (surprise) but the Canterbury sports top seems to have been successfully marketed to the youth as an expensive, fashionable replacement. But at least and at last the boys are warm.
(Some of the old stuff's coming back. My sixteen year old has just bought a black trenchcoat - very smart. I'm hoping he'll invest in a low-brimmed hat as well).
