The Mystery Ranch Chestie Mil Sternum Strap is exactly what it sounds like… it’s a replacement sternum strap for Mystery Ranch backpacks. It also turns out that it fits perfectly on the shoulder strap MOLLE on GROUCK bags.
The quality of the strap is exactly what you’d expect from Mystery Ranch. It’s well put together and I haven’t had any issues with it yet. It served me well at GORUCK Heavy 009 and I’m glad I had it on my GR2 because there were many times that I was pushing 70+ pounds. The plastic connectors that go through the MOLLE hold in place really well and you almost need a key or knife to pop them open once they are closed. This is good to note so that you don’t start playing around with it and end up locking the edges.
The sternum strap is not cheap at $15 a pop (before the ~$10 shipping cost.) If you want to buy one I’d highly recommend getting a group of people together and placing a bulk order. The increase in shipping in minuscule and I think you can order 12 sternum straps for $1 more shipping than the cost one 1 sternum strap.
I would say that a sternum strap can be very beneficial to your comfort when doing a GORUCK Challenge. Is the Mystery Ranch Chestie Mil the best one to get? That’s debatable… especially when you factor in the price. Your other option is to give Maxpedition a call and ask for one of their replacement sternum straps ($11 shipped) and you’ll end up saving a good deal of money. Personally I prefer the Mystery Ranch one over Maxpedition but to some it may not be worth an extra $13+.
If you’d like to purchase a Mystery Ranch Chestie Mil Sternum Strap you can do so by ordering through Mystery Ranch’s online store. Just remember that there is a decent shipping cost attached to the price of one strap.
I have used the Mystery Ranch Chestie Mil Sternum Strap in the following events:
GORUCK Heavy 009
During GORUCK Heavy 009 we had to bring a good deal of extra equipment which brought the average pack weight up to over 50 pounds. On top of that we had to carry sandbags and extra weight which really put a strain on the back & shoulders. The sternum strap did exactly what it was supposed to do and made carrying all of that a good deal better.
