This speed belt is fantastic for securely and comfortably storing gear on your waist. If you want to be able to swap out lenses, stash a water bottle, store extra batteries but don't want to carry a backpack, wearing it on your waist is a great solution. Can lock bags in place or let them slide around so you can adjust where they sit on your waist throughout the day.
Adjustable to easily loosen without unclipping completely.
They make this one and a smaller Think Skin Belt. I prefer the extra cushion on the Pro Speed Belt.
