Frequenty Asked Questions

We're moving to a kitted system so that we can design and build packs and frames that are optimized for integration based on the function of the product. There are some cool new things in the works. In the mean time, we may be able to accommodate pack only orders based on available inventory - contact MR Customer Service or call 406-585-1428

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.

The only repair that we can offer on Dana Design products is a replacement back foam pad on packs with the ArcFlex body panel design. We can ship the foam to you and you can easily install it yourself without having to send the pack in to be repaired. Replacement back foam pads are $15.00 plus $5.00 for shipping.

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 406-585-1428.

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.

Mystery Ranch accepts returns for a refund within 60 days of the original purchase date. Items must be returned in brand new, unused condition, and shipping charges are non-refundable. Please give us a call at 406-585-1428, and we can get you set up with a Return Authorization (RA#).

If you think that you qualify for a pro discount, please give us a call at 406-585-1428. Thanks!

If you are in need of a different size yoke or waist belt, please give us a call at 406-585-1428.

Why did you add a production facility in the Philippines?

We added a production facility at Clark Field in the Philippines because we needed the capacity to build for customers both domestic and abroad who don't require (Berry compliant) U.S. production and / or don't want to pay a premium for products built in the U.S.A

How do I know if the pack I want is made in the US or PI?

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. We still seek out the highest quality materials and construction methods available. We have rigorously run through every product and inspected them ourselves to certify the quality of a good matches our US standards. The quality is the same, so much that we have to mark the product so we don't confuse the two ourselves. Our distributors who have received product from the U.S. and from Clark Field have not been able to tell the difference without looking at the label.

How do you ensure the quality is the same?

Our sewers at Clark Field are trained using the same protocol we use in the United States. We spend the time to send our trainers and inspectors to the P.I. to consult and educate the sewers on our methods and quality standards. The short of it: PI production workers are trained by our people, they are our people.

Will Warranty or Repair procedures change?

No, our warranty and repair will remain the same regardless of production location. We hang our hat on being the most durable and comfortable packs on the market and that will not change.

I bought the terraplane in 96 and ran it through 5 seasons of harsh backcountry trail work in the High Sierra. Schlept it around mexico. Off and on planes and busses. Had kids in 2008, drug this pack out of the garage in 2015. Was about to buy a new pack but this one just feels to good still! Gonna have a couple straps replaced that the dog ate and i think ill get another 3 years out of it.
I still have my original 1996 Dana Designs Terraplane OK, handmade in Bozeman, Montana. It fits like a tailored suit and, thanks to the brilliant ArcFlex system, makes a 90lb load feel like 60lb. The 1000D fabric is pretty bomber, too. It's great to see that Mr. Dana Gleason is still working his magic. Yes, the pack is heavy but it's built to last and to withstand the harshest conditions. The heavy duty, nickel plated YKK zippers are still perfect. The original accessories, like the Wet Rib bottle holder/snack/camera pocket, the Beaver Tail, extra side pockets and the hooded pack fly are all still part of my current gear set today. For long, remote mountain trips, nothing beats a Terraplane.
Purchased my Dana pack in 1996 and still continue to use it; it looks brand new! I've taken many, many backpacks and the load-level straps are amazing! The quality, the build, I would not part with this pack even though it is heavy. I've know many individuals whose "light" packs disintegrated in the field! Just wish I could figure a way to hook up my bladder (I currently use the back pocket for my bladder). Thank you for building a bomb-proof pack!
