Overview
The trakFIT leg loops on this Black Diamond Momentum kids harness adjust to a child's legs, and the buckle comes pre-threaded. It is lightweight ripstop nylon and polyester, for indoor and outdoor climbing.
A pre-threaded buckle saves a mistake at the base of a climb, and one size covers a range of growing children. The limitation is the narrow weight band: the description targets lighter children, and a maximum weight limits how long they can use it.
Who it's for
Children in gym classes, outdoor programs and family climbing days. Older kids, teens and adults should buy an adult harness.
Pros and cons
- TrakFIT adjustable leg loops
- Lightweight ripstop fabric
- Two year warranty
- Narrow child weight range
- Hand wash only
- Gear loop details missing
Performance notes
Adjustable leg loops let the harness be set to a child's leg size, which reduces slipping and pressure. Ripstop fabric resists snags and tears at the edges. A pre-threaded buckle lowers the risk of a threading error, though every harness still needs a partner check before climbing.
