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. 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. ### ⭐⭐⭐⭐⭐ Works well *by G***S on May 26, 2024* 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. It seems sturdy and has good adjustability. ### ⭐⭐⭐⭐ Maybe get the GoRuck strap if you’re rucking… *by J***M on June 10, 2026* The sternum strap is pretty good. It attached easily to my GoRuck Basic Rucker. It holds well up to about 25lb, but when I get up to 30lb+, it starts to slip a little bit. I find I’m having to constantly tighten it on rucks. If you’re using it on just a regular backpack with not a lot of weight, it’ll probably be fine! ## Frequently Bought Together - YYST Sternum Strap Backpack Chest Harness for Backpack with 20MM or 25MM Webbing - Wisdompro Backpack Chest Strap, Heavy Duty Adjustable Backpack Sternum Strap Chest Belt with Quick Release Buckle --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.sa/products/69313035-yyst-sternum-strap-backpack-chest-harness-for-backpack-with-20mm](https://www.desertcart.com.sa/products/69313035-yyst-sternum-strap-backpack-chest-harness-for-backpack-with-20mm) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-09-10*
