The bungees on the Ruck young style work better than the strap style, IMO. Don’t have to worry about twists, and don’t even know you’re wearing it. Every chest pouch I tried ended up in my way and being hard to get on/off/just right. Couldn’t move them to my off side, wear regular, stuff in a backpack or jacket pocket, etc. Chest harnesses just seem like trying to make the simple into something overly complicated.
