air-inflated WalkAround mascots
WalkArounds bring in over 100 cubic feet of fresh air every minute, which can be directed onto the wearer through the use of the KoolTube. Circulating fresh air surrounds the wearer - and the open space inside allows the wearer to carry and drink from a water bottle.
traditional "fuzzy" costumes
The conditions inside a fuzzy costume with temperature and humidity can easily reach a Heat Index of several hundred degrees! NOAA lists Heat Stroke as "highly likely" at Heat Indexes over 135 degrees.
Try this in August: put on a wetsuit and put some pet hair inside of it, then a pair of jeans, a sweater, ski pants, a jacket, a pair of size 24 clown shoes, a floor-length fur coat - then a ski mask. Finally, duct tape a brick on your head (fuzzy heads can weigh up to 20lbs!). Now, go out in the sun and dance around. When you've had enough, take everything off and buy a WalkAround.
