Amazon.com : Wisdompro Backpack Chest Strap, Heavy Duty Adjustable Backpack Sternum Strap Chest Belt with Quick Release Buckle for Hiking and Jogging - with Slide Locks (Gray) : Sports & Outdoors

I bought this to add to my Osprey Arcane 30L duffle/backpack.Pros:* They work for these backpack straps, which have no included attachment points for a sternum strap* Materials are good* Buckles are goodCons:* Adjusting the straps is very fiddly and requires a repetitive fit/take off the backpack/adjust/try again/repeat process.* There's no easy way to adjust the sternum straps while you're wearing them. The only adjustment is the same adjustment that allows the sternum strap to fit around the backpack strap. To make the adjustable while wearing the backpack would require a second strap loop and buckle dedicated to that purpose. These don't have that.* The straps are very long, which means you need to figure out what to do with all of the extra strap flopping around. I'll leave that as an exercise for the reader, but it's possible to do with a fair amount of fiddling around. I imagine they're long to enable you to use them at the waist if you want, but I wouldn't expect these thin straps to bear any weight on your hips. At best, they'd help keep the backpack against your lower back, a problem that doesn't exist for me and my body shape.* There are no keepers for the excess strap, aside from the packing rubber bands, which I imagine will break quickly and don't do a great job of securing the excess.

Got this because I wanted to find a cheap way to get into rucking. Works well for walking speed but when I start to jog, the straps even at the tightest setting do not fully stop your backpack from bouncing. Definitely a good product for the price
