Today’s invention is a simple way to reduce the heat lost by your gloved fingers by about a third.
It also allows me to indulge my limitless admiration for the zip fastener (again).
Each adjacent pair of glove fingers has a zip on the outer surface between them, which can be used to join the fingers together; reducing their area and heat loss.
This also allows e.g. the index finger to be separated occasionally for increased dexterity…just as long as that doesn’t involve something so stupid as operating a trigger.
