In the meantime, we may be able to accommodate pack only orders based on available inventory - contact MR Customer Service or call 1.833.548.1999

As much as we would like to be able to offer our military/LE/ firefighter customers a discount on our packs, we have government contracts in these markets that prevent us from doing so.

We are not set up to perform custom work on individual orders and no, we cannot build a pack for you in a custom color. If your concern is in regards to sizing please give us a call at 406.548.3234.

Also, please know that modifying your MYSTERY RANCH pack may void the lifetime warranty, so please think first before you start ripping straps off and cutting holes in your pack to make it more aerodynamic for winged flight.

First, start by washing your pack with hot water in the shower. Use a mild detergent like Dawn to get minor dirt and grime out of your pack. Dry the pack out of direct sunlight. DO NOT USE HARSH CHEMICALS TO CLEAN YOUR PACK. If you need to get odors/blood out of your hunting pack, please use Atsko Sport-Wash Laundry Detergent

We always recommend that you size down for the waist belt. If you fall in-between sizes on the yoke, we recommend that you size up.

Why did you add a production facility in the Philippines and Vietnam?

MYSTERY RANCH added these facilities because of the increased demand for our product. We needed the additional facilities to build for customers who don't require (Berry Compliant) US production and / or don't want to pay a premium price for products built in the U.S.A. With these additional offshore facilities, we are able to focus our domestic facilities on the Berry Compliant orders.

How do I know if the pack I want is made in the US, PH, or VN?

It will be noted on the product page on our website and you are always welcome to call us and ask if you don't see the "US" or "world" icons that denote production location.

Is the quality of the packs the same?

Yes, absolutely! We carefully select the highest quality materials and ensure that all production facilities adopt our quality standards and techniques to deliver products consistent with the MYSTERY RANCH legacy. Our distributors who have received product from the US, PH, or VN are unable to tell the difference without looking at the label.

How do you ensure consistent quality?

Our factory resources use the protocol defined by our team in our production packages in order to deliver consistent quality gear. Upon introduction of new products, our product engineers visit our factory resources to work with them to develop new styles. As the product goes to production, our QA and QC teams will then visit our US, PH, and VN factories to ensure the finished goods meet our MYSTERY RANCH standards.

I like the classic outline and add new label located at outside, show "MADE in USA".
Although the product i selected is currently unavailable, but I will never give up to check the web everyday.
Thank Mystery ranch to provide excellent product in the World.
I purchased this bag with the intention of using it as an everyday bag to go with me anytime I leave the house. I pack a simple change of clothes, a snack, deodorant, my firearm, multitool, pocket knife and some pen and paper. There's is still a lot of room left for anything else I'd need to stowe away during my course of the day. This bag is big but can be cinched down and it becomes a very mobile transportable everyday bag. It has been worth every penny. The materials and craftsmanship makes you proud to own one! If anyone is looking at this as just an EDC bag and you don't go hiking much if at all this bag will fill that EDC role and perform amazingly. Its the most comfortable high end bag I've used to date.
I like this bag a lot. I use it daily, for school (college), regularly on hikes, trips, camping, biking, etc, and it meets every need. It's made well, out of durable materials. I don't worry about damaging it on anything, nor do I worry about the things inside the bag getting damaged (when used within reason, of course). It's not an lightweight bag though, just in case you weren't aware of that. That being said, it's not overly heavy for it's construction, and it's zippers are top of the line. I bought it with the padded waistband, which is a must if you are putting any meaningful weight inside, because between the should straps and the waistband, loads are carried very comfortably, easily, and securely for long periods of time. The top lid does tend to flop down over the main pocket then I don't want it to, but that's not a big problem, just a minor annoyance. Also, the strap lengths are quite long, and I'm not a big fan of the roll-over-velcro-up retention system, because it can make adjusting straps troublesome. Owner for nearly a year, and feel this deserves 5 stars, for completely meeting my expectations.
