We love our storm joggers! The material is super soft on both the outside and the inside, making sure your babe is extra cozy this fall/winter. The fabric has just the right amount of stretch, and the functional pocket is a kid favorite, so I really love that added touch! My little guy is 35 lbs and 37 inches tall, we are typically in a size 3/4 in bottoms, but sized down to a 2/3. We were still able to roll the waist once, so these will last us all winter and possibly into next!
