Sportime connectable crawl-through tunnel is used for gym or classroom activities, and has a ripstop nylon shell for durability. Nylon is very strong and flexible, has excellent abrasion resistance, is lightweight, and resists crushing and cracking. The tunnel is multi-colored for visual appeal, and is collapsible for ease of storage and transport. The tunnel measures 3.0’ in diameter, and 12.0’ (L). (L is length, the horizontal distance from left to right.) The tunnel can be attached end-to-end with additional tunnels (sold separately) to expand and create curved pathways, and is suitable for age 3 and older.
