These right here are pretty straightforward: if you’ve got a USB power source, you can keep your fingers warm. Good for typing, smartphone use, and of particular indication for those with poor circulation in the extremities - for whatever or whenever one can imagine needing warm, non-numbed-by-cold fingers.
This year’s version comes equipped with a timer, a stretchy-contracty one-size-fits-all and easy-on/off construction, and connector plugs near the gloves themselves to minimize cord tangle.
