Reinforce Resistive Awareness While Encouraging Creative Movement. Watch children and adults alike become enraptured as they begin to understand and explore the three-dimensional space they individually occupy. Body Sox are designed specifically for spatial awareness through balance and resistance. X-Large size pillowcase-like sack, is constructed from four-way stretch Lycra® with a reinforced hook and loop-closed entrance. Once inside, users find themselves in a private domain that begs for kinesthetic exploration. As they move their shapes become amorphous and art-like. Because the Lycra® is translucent they can see the shapes being created around them. Assorted Colors. Fits 2 - 3 years old. Made in the USA.
