Yeah you get used to it.. You only get so warm.. The trick to say ten hours straight or longer is LOTS and LOTS of water.. lol.. Fringe festival I used up about 4 of the 6 liters in my camelback system.. Also another good trick is potassium loss (sweat) so bananna really help and your electrolyte count will be bad (sweat again) so Gatorade or equivalent.. I like to add a can of Red Bull to help wind you back up after say five to six hours straight, really helps.. My record is suited up just before 10 am, went all day in suit, did a fursuit parade, Dance competition, Rave later and parties and finally got out at just before 4 am.. You tend to live in fur at the cons, well I do. .ha ha...
