It was easy to put on and seems to be the same design and quality of the Goruck brand. It really improves the weight distribution and feels much better going for long walks now. Review: Works well - I bought this for my Yeti backpack soft cooler. Can't believe that for the price, Yeti did not include a chest strap. This strap fit the Molle's on the shoulder strap perfectly.

But easily adjusted to different lengths. **Q: Is this strong enough to ruck 30+ lb? Is there any warranty if the buckle breaks?** A: I would say it would work if your straps are thick on your pack (the straps that will slide in the buckles). The buckles that slide on my bag keep popping off because my webbing that I'm using on my bag is thinner than the plastic "slide on" buckles, so they keep popping off, it's pretty annoying. **Q: How narrow can this be tightened?** A: Not much less than 3 inches between backpack straps. The buckle itself takes up about 2 in ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Sternum Strap *by L***N on July 31, 2025* Works great for my Goruck Rucker 21L.
