Lanyard systems for night vision devices are very important. There are a number of excellent ones on the market, but many of them are pricey, and it isn’t always intuitive to hook them up to your night vision device once it’s mounted to the helmet.
Since it’s generally not a good idea to store night vision attached to the helmet, we wanted a tie off that could be easily attached to the helmet once the night vision was added, and then easily removed when needed.
So we created the SBL.





The SBL lanyard attaches to the NVG via shock cord, and the lanyard then velcros to the helmet. Fast. Simple. And the SBL can remain attached on the NVG when it’s stored. Simply attach the NVG to the mount on your helmet, and then stretch the SBL to one of the velcro panels on your helmet.
This will retain the night vision if it takes a dump from the mount, or the mount falls from the helmet. With all that said, we don’t recommend this system for HALO jumping as a dedicated tie-off. But for ground operations, it’s very effective.
The SBL also has three elastic cells on top for batteries. Which can be handy for backup AAs or CR123As.


The SBL can also be used to retain battery packs on the back of helmets. The standard velcro that comes with battery packs is NEVER enough to keep it on the helmet. An additional piece of shock cord and an adhesive velcro patch is included. Simply run the shock cord on each side of the SBL around your ear-pro mounts, and slap the velcro on the front of your battery pack.
