We need a gamer glove, perhaps even a full bodysuit, with built-in air conditioning for the Sweaty Gamer at home. And it should have a combined superhydrooleophobic microtexture coating to wick away that Gamer Grease. Headphones and VR headsets also need this coating.
They should just look into the furry market then. No seriously; some of the better cooling and sweat-reduction gear have been pioneered by determined furries who want to live near-full time in their fursuits. Some of their products have since made it into construction and military sectors. No such thing as a backpack AC for a full-body suit yet, but it's been one of their long term goals, much like it has been for the military and industrial sector too.
I only know this because I looked into cooling gear I could wear while in a full body Halloween costume that I used to volunteer for at my local community Halloween bash (until C19 happened, and then they never brought it back).
EZ Cooling Vests is one of those I've tried and used, and they work well for some cooling. Paired with sports-based moisture wicking layers, it helped a lot.
