I got one a few months ago and tried it out. It definitely helps spread out the load on my back.
I have been telling everyone I know that has a heavy load to carry. This works! Get one if you are on the fence. Your Back will thank you!
Purchased due to riding long hours on patrol, love it, keepers are perfect size, works great with the lumbar support in the seat, recommend for anyone with minor back pain from sitting or cause of the duty belt.
