Garmin Backpack tether

The durable nylon harness wrap with hook-n-loop attachment can accommodate any style of strap with widths up to 9.5 cm (3.75″) and is Modular Lightweight Load-carrying Equipment (MOLLE) compatible.
The same hook-n-loop material also is used to easily stow your compatible Garmin device for optimal GPS performance while still providing access at a moment’s notice.
When the device is detached from the hook-n-loop, the spine mount and lanyard cord - adjustable in length from 5.1 cm to 61 cm (2″ to 24″) - ensure the device will stay with you at all times.

A Cradle Mount accessory is required when used with the inReach® Messenger or inReach Messenger Plus devices.
