Most furries think that seeing any area of skin is 'breaking the illusion', so you have fur down to your neck on a fursuit head. Then remember the logistics of it. You can't fursuit in the rain.. so it'll most likely be a nice day. You've also put, essentially, a 5 to 10 inch thick head of fur and foam on your head, with the only ventilation being through eye mesh. You also have your hands covered in fur, your feet lugging big paws around and occasionally have a huge tail which weighs you down. That said, it's still actually quite fun. I sold my fursuit, but here I am wearing it...
