“undergarment” is a bit impractical but you can put on a harness of tubes hooked up to a PC watercoooling system and carry around a big battery. some tryhard cosplayers have been doing it for at least a decade.
I helped build something like this for a race car a few years ago. The commercial version is called a Cool Suit and uses a cooler full of ice water. We used a bunch of tubing sewn onto an old pillow case, and plumbing fittings from Ace Hardware, with a 12V bilge pump. It was pretty effective.
I kinda want to build a light-weight version so I can ride my bike when it’s 100F outside.
