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

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 am an Engjneer for a County Fire Department in Southern California. I have used this pack for about 3 months and am assigned to a Station that has a type 1 engine and we cross staff a type 3 engine. This pack is awesome for initial attack on brush fires. It is comfortable, adjustable, and accommodates wearing a hose pack well.

Pro’s: the mystery ranch harness is very comfortable and they added a pull away from your body system to tighten the waist which is very nice because it makes it easy to adjust the waist while wearing it. The pack holds the shelter tight so that it does not sway and the hydration bladder being at your lower back makes accommodating a hose pack easy. The hydration bladder has a shut off valve at the bite valve which prevents it from leaking as well as a dust Cap. It also has a one way valve where the hose meets the bladder so you can remove and refill the bladder without unthreading the hose.

Cons: storage space is the biggest con. If they had doubled the storage space to 500 cu in. I would have given the pack 5 stars. It barely has enough room to accommodate a headlamp, my face shield, and a few cliff bars. I bought the hot lid to go with it which is nice to use if I need to add anything else for a long day. The other con is that to accommodate fuses you either need to take the end caps off that allow you to attach the fusses together, or you need to find the shorter helitak fusees.

Overall, this pack is amazing and is in my opinion the best back available for Engine operations. It is well worth the money for anybody who does this professsionally.
I work for a County Fire Department in Southern California and have had this pack for 3 months now. I have used Fss, true north, ruffian, and coaxsher. This is my favorite pack so far. This pack is perfect for Engine Companies on initial attack. The pack fits comfortably, is nicely padded, and accommodates a hose pack nicely. Storage space is minimal so I bought the hot lid for days when I will be away from the Engine for a while. If you want to hold fusees in it you need to either take off the connection ends or find the shorter helitak fusees as normal fusees will stick out. The hydrapak hydration bladder that comes with it has some nice features that I wasn’t expecting. It has a twist off shut off valve which is nice because it won’t leak. It also has a one way valve for the bladder bag so you can disconnect the hose from the bladder without it leaking and refill your bag while leaving the hose on your pack. I gave it 4 stars instead of 5 because of storage space. If the storage space was doubled to 500 cu in. It would get five stars.
I don't write reviews until the product is put to use in fire condintions. I had the pack on for 12 hours and did not feel it all. It was comfortable fit and fit well with the Wolfpack hose packs. Storage is minimal so I bought the additional storage for a mop up kit which fit well and snug. I highly recommend it.
It allows for proper heat release on the back so my back was not super sweaty like other packs I have used.
