How do you keep your kids protected against the rainy season especially when they go to school?

My mom was always making sure that I have a raincoat in my bag during my grade school years. I remember, she was even buying new ones twice a year to excite me. One funny trivia: There were times when I was a kid that I would stay in our garden and wait for the rain. Why? To try my new raincoat! Consider it weird but I was in love with the feeling of getting it drenched by the rain.
