Blanket - fleece jacket

Let's call this a -SegJaka- - or a blanket like a jacket. Babies explore the world through their hands, but when covered with a blanket in cool moments, this is not possible. -SegJaka- is a combination of a warm blanket and a jacket, keeping the baby warm with free hands. Useful in a home chair, stroller - the blanket gets kicked off and the baby is exposed to coolness again, but with -SegJaka- it won't disappear anywhere. In the car seat - how often does it happen that a covered baby kicks off the blanket and it ends up on the car floor (?) -SegJakas- are made from warm fleece fabric.
