MyFishFinder.com Just like iceshanty but warmer

Check out the bogs snowboots for kids. They worked great for keeping my daughter warm. The snow suits I pieced together. Problem is they grow so fast you don’t want to drop a lot of money on tiny pants they only wear for one season. I would check second hand shops. Some rich grandma probably dropped some money on some tiney Patagonia pants
