Sell me on wool. I'm not sure I get the idea.

I see all the longies and leg warmers and stuff and they're all SO cute. Although I don't understand really their function... do you put them on over dipes? are they just for cold weather? I live in Florida, and it was 80 today in Feb. so would I ever even use them? I've also heard people talk about keep LO dry and containing leaks... where's that come into play? Sorry for all the questions, wool is just confusing for me. lol
