REI Leash Connector features a carabiner and a D ring on each end to offer flexible usage, including a cross-body configuration for MELLEM and NOMAD or as a connector to other gear, such as a dog walking belt. It comes in 2 widths - REI (narrow connector) and REI X (wide connector).
The REI X wide leash connector is recommended for the cross-body configuration of the NOMAD as its D ring allows for a long line to pass through.
