The UBPRS was designed out of necessity, allowing the end user to secure any battery pack to their helmet, quickly and efficiently, minimizing bulk and maximizing usable ID space for patches and identifiers.
The UBPRS' measurements are 3.5"x2" and has cable management elastic loops that can be run either topside or bottom-side.
Apply the included adhesive velcro to your battery pack, then attach the hook side of the UBPRS on top of it - they will interface keeping it secure in all conditions.
-Portable chargers for thermal or night vision recorders can also be used (USB type lithium battery packs) but typically require an extra piece of adhesive hook velcro to interface with the helmet (on the underside of the battery).
For added retention, use a hi/lo ring to lanyard your battery pack to the strap.
(HI/LO) rings sold separately.
