2 year old Winter Wear

What’s the best snowsuit* for daycare? Thermoball bunting? Thinking NON BULKY but still down filled and very warm. Will be worn outside to play above 35 degrees. Needs to be waterproof and available in a size around 2! Trying to avoid the cheap bulky suits she can’t move in like last year. Want something that she can run and slide in still! 🙂
