I just try to lead by example by always wearing my helmet and jacket no matter what the weather is like (hot, cold, wet, dry). My helmet and jacket have vents which help as long as I'm moving. One of my brother-in-law's friends saw me pull up on a really hot day with all my gear on and called me 'Mr Safety'. I just shrugged, smiled and said 'Yep, that's me.' I've been down before and I'd rather be safe than sorry.
