We have always used the Boden shaggy zip through jackets too. They are so plain this year though. Usually they are stars or some other cute print. I'm glad I have hand me downs this year...plain is great for my oldest. We move from that to fleece jackets (usually some bright North Face color), to winter. Any kind of hoodie sweatshirt works when it's just for cool mornings and warm afternoons though honestly. We've used the Hanna version before too.
My younger kids have never lost a jacket, but they do go to a very small school. It's my older one who leaves sweatshirts behind all the time, but I always find them in Lost and Found.
