Fursuits always look so hot and uncomfortable to me. Can any furries here confirm or deny?
Can confirm.
In fact, furries went out and improved upon the design of military cooling vests to try and beat the heat:
They are in fact hot, but there’s ways to be comfortable in a fursuit, such as wearing underarmour/lycra/spandex. Sweat wicking stuff is a life saver in a fursuit.
They definitely are. Cons always have a lot of signage up about watching for symptoms of heat stroke, and decent cons will have a “headless lounge” set up as semi-private (fursuiters and assistants only) space to take off parts of your suit and cool down. Usually lots of fans going and freely available water.
