For our 3 year old daughter we had ordered this reflector union. Direct unpack, we noticed the poor workmanship. The nylon fabric is skewed and asymmetrical cut, not running the curves smoothly and reflective patches attached asymmetrically. After all, like the lion head of our daughter. Unfortunately, they can not use it (yet), as it constantly slips while wearing his shoulders. We think, from about 6 or seven years it seems to work. A rubber coating of the shoulders at the bottom would help as well as a weighting at the ends of the front and back. Because he blows also in light winds high, tangled and has no effect.
