9 Best Kids Climbing Harnesses 2025 in the United States

The PETZL MACCHU Kids' Climbing Harness is a well-rounded product designed for children under 40kg (88 lbs). One of its biggest strengths is its adjustability. The harness can be easily adjusted to fit a wide range of sizes, growing with your child, which means you won't need to buy a new harness every year. This makes it a cost-effective choice for parents. Another highlight is the cushioned comfort, thanks to its padded waistbelt and leg loops, which are made with the same ENDOFRAME construction used in Petzl’s adult models. This ensures that children can climb comfortably without experiencing chafing or discomfort.

Safety is also a priority with this harness. It features a belay loop, gear loops, DOUBLEBACK buckles for secure size adjustments, and droppable elastic stays for leg loops. Additionally, it can be converted into a full-body harness with the addition of Petzl BODY shoulder straps (sold separately), elevating the child’s center of gravity to reduce the risk of inversion during a fall.

One potential drawback is the necessity for hand washing, which might be seen as inconvenient for some parents. Furthermore, while the harness is highly adjustable, it is a 'one size' product, which might not be the perfect fit for every child initially. The PETZL MACCHU Kids' Climbing Harness is an excellent choice for parents looking for a safe, comfortable, and adjustable climbing harness for their children.

The PETZL OUISTITI Kids' Harness is a full-body harness designed for children under 30kg/66 lbs. Its one-size design is highly adjustable, featuring DOUBLEBACK buckles on the shoulder straps and back. These adjustments are out of the child's reach, ensuring safety.

The harness's ease of use is a highlight, with an orange dorsal point that simplifies putting it on and color-coded construction for clear orientation. The comfort is addressed with quilted closed-cell foam on the leg loops, waistbelt, and shoulder straps, making it suitable for longer wear during climbs.

Safety features are robust, thanks to its semi-rigid structure and high-strength polyester materials. One potential drawback is that it needs hand washing, which might be less convenient for parents. This harness is particularly beneficial for young, beginner climbers who need a secure and comfortable fit with easy adjustments.

The Black Diamond Momentum Kids Full Body Rock Climbing Harness is a reliable option for young climbers. One of the standout features is its high tie-in point, which helps keep kids upright, an essential safety aspect. The harness is designed to be easily adjustable, making it convenient for parents to get the right fit for their child. Its construction focuses on comfort, minimizing pressure points, which is crucial for young users who may not be accustomed to wearing climbing gear for extended periods.

The one-size-fits-all approach simplifies the buying process but might not cater perfectly to all body types. The material used is plastic, which ensures lightweight and ease of movement, though it might not be as durable as other materials like nylon. Hand washing is required for maintenance, which may be less convenient compared to machine washable options.

With a solid warranty backing from the manufacturer, parents can feel secure in their purchase. This harness is particularly beneficial for those new to climbing and looking for a straightforward, comfortable, and safe option for their children.
