Great addition to my setup- i run the older Pro-M with an airframe harness, but things get bulky when i have a chest holster, airframe harness, and pack straps. This eliminates a layer, making it easier on my shoulders and collar bones when on a long hike. Easy to snap and unsnap Pro-M when donning and doffing. The system was easy to install on my pack and adjusted easy too. I’m able to still run the Molle wings as well. The only thing that was a bummer is the kit was missing one bino hanger, but FHF sent a replacement quickly when contacted. I wish they would stop using an AI bot for customer service though- it would be nice to communicate with a real person. That has nothing to do with the gear tho, which works great.
