Pre-Threaded Auto-Locking Buckles One size fits all Recommended for children 3 to 8 years old not exceeding 85 lbs. Climbing is a fantastic activity for young kids! Start them early but keep them safe with the Bambino full-body harness. Six points of adjustment allow the harness to be fine-tuned for a wide range of body styles and sizes. A single tie-in point at the sternum keeps the child positioned upright while hanging. The pre-threaded auto-locking buckles are quick, safe and easy to adjust and elastic retainers keep fidgeting fingers from loosening things when you aren’t looking. Color-coding on the leg loops, waist belt and tie-in point make fitting the Bambino a breeze and further reduce the potential for user error.
