At 61 years old I relax solo backpacking without a tent in the backcountry wilderness during all four seasons. Due to my work as the chief scientist of a Whitefish Montana biotech whose therapeutic focus is Glioblastoma brain cancer, I need to maintain daily contact with my research team through satellite communications when I am in the Montana wilderness. The rechargeable batteries on the many devices I carry must be recharged using portable solar panels. I therefore carry a lot of gear to sustain myself in remote wilderness areas for several days or weeks at a time. No other pack I have used carries heavy loads reliably and comfortably like the MR 7500. Other packs become uncomfortable for me at 65-70 pounds, whereas the 7500 carries comfortably on me up past 80 pounds. I use one MRE a day for food in the backcountry (two a day in winter) and the 7500 enables me to carry plenty of food. I have used the Dana Terraplane and Astraplane for years, also the Gregory Denali Pro (including the newer Gregory Denali 75 and Gregory Denali 100). The Denali 75/100 are great packs for loads up to 60-65 pounds or less but the 7500 is in another league of its on. Its very easy to adjust and load. Kudos to Mystery Ranch.

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 meantime, 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 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've been working as a therapeutic guide for the last 4 years, and have spent more than 3 years of trail time with this pack and it has taken all the abuse I've put it through and come out with only one wear spot. To me this means the stitch work, and construction is of the highest quality. I appreciate the ability to call for buckle replacements and the awesome service. This pack has been a tried and true cornerstone to my backcountry experience. Thank you Mystery Ranch for the awesome pack!
I was in the United States Marine Corps for 10 years. I was on a recon team and was issued this very pack. After countless missions in the jungles, desserts, deep oceans, and other inhospitable places I can say this bag is AMAZING. I could put my whole kit into this pack and not worry about seams exploding or my gear being thrown around. I recently got out of the military and am working for a private contracting business and use my same pack for extended patrols and long distance hikes deep in the mountains. I will NEVER use any other pack. I am not nice to my gear and use and abuse gear as it should be used and abused. I have never had to replace my pack because of the amazing quality and workmanship. My pack has been around the world 7 times in more countries I can count and have worn it for more hours than another pack. If you are on the fence hop off and buy this pack. It will change the way you look at backpacks.
