My 2 1/2 and 5 1/2 year old grandkids wear this for the backyard zip line and it works great. Especially for the little one that tries to hang upside down and was letting go unexpectedly on the saucer swing we previously used. Now I am comfortable with them going the full height and length of the line. Seems like there is plenty of grow room for both of them.
