I had ordered the bino harness first. Could not believe how lite and well made it was. So next I ordered the belt and lumbar pack with a stretch pouch. It is perfect. It too the whole system is super lite. The quality is second to none. I compared it with a few other makers who's were more than twice the price. No comparison. Marsupial
Pocket is small and only the front material is stretchy. Works great for what I wanted it for though
Purchased two of these for my Mystery Ranch pack. These are high quality pouches and are fit very secure on the hip pads on the pack.
