A great new design that's really two boots in one, the Rainbou is year-round rainwear that's as happy jumping in winter rain as it is summer showers. It is built from vulcanized rubber for a completely waterproof & seriously durable shell that stands up to rough wear on kid's feet. Inside, a removable liner provides insulation on cold days, but pulls out easily for the perfect warm weather rain boot. The result is a versatile boot that's comfortable across a wide temperature range, like having two boots in one.
