Peak Design Field Pouch V2, Charcoal, 2-in-1 Organizer and Sling Bag, Adjustable Shoulder Strap and Integrated Belt Loops, Weatherproof Nylon Canvas, Organizer Pouch or Carry Bag for Men and Women

The bag itself is of good quality. The strap definitely seems like an afterthought or as if it was included just because. The problem I had is the bag is much too narrow to contain anything that isn't a tiny accessory like a battery or an SD card. Why you would want to only carry those items in a sling bag is curious to me. There are much better options for pouches to contain only small items that will even fit a power bank or an iPad mini as well. This one just doesn't open wide enough. Also while the velcro is strong when you have items in the bag the velcro is difficult to line up and doesn't feel secure enough, certainly not as secure as a zip. I think it might be good for someone with a very specific purpose but it's an awkward between a sling bag and a tech pouch and is ultimately not great at being either. I've returned it.
