I hit a deer in April 2008 and had all the gear, FF helmet, armored jacket, gloves, boots. Pitch dark at 9:00PM on a two lane road with poor lighting. Hit the deer then a mailbox, the front wheel stopped in a drain ditch and I landed about 15 feet from the bike in the drain ditch. Bike was totaled (see photos), I had broken collar bone, broken shoulder blade, a few stiches from a jacket grommet cutting into my arm and a bunch of bruises. ATGATT for me, if I didn't have the gear, can't believe I would have escaped with minimal medical problems. According to Wisconsin DOT 2% of car-deer accidents end up in human fatalities versus 84.9% of motorcycles-deer encounters end up in fatalities.
BTW, the nurses and doc's in the ER at Metro General cheered when they found I had wore all the gear, a week earlier a MC-deer fatality occurred with a rider without the gear. I beat the odds.
