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 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.

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. For any other Dana Design pack repairs, please contact Marmot or try the following reputable gear repair companies:

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

For full cleaning and care instructions, see here

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 1.833.548.1999, 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 1.833.548.1999.

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 bought a Kletterwerks top loading pack just like this in 1978; on mine the shoulder straps are pulled up rather than down to tighten. I bought two accessory pockets that attach to the compression straps on either side of the pack. I used it in Idaho for cross-country skiing and working for the Forest Service (it has a few little flecks of tree marking paint on it) and in Antarctica during my stints in support of the US research stations there. Although the pack has been retired for some years, a couple of years ago I saw fit to replace the zipper on the small top pocket, as it had separated. The pack really is still in excellent condition - it was extremely well built to begin with. I might want to bring it out of retirement...would that a padded laptop sleeve could be added to my vintage pack - that was a nice addition to bring the pack into the 21st century; it would then be the perfect daypack for knocking around town, especially on days when one might need a rain jacket or an extra layer. I always also carry a first aid kit wherever I go, and this pack would accommodate that with ease.

If you like solid construction and a well-conceived minimalist design, this would be an excellent pack that might just last a lifetime.
I bought a kletterwerks in 1979. I loved the rear pocket with foam in it. I spent the summer and fall in Yellowstone working and geyser gazing. I would pull out the pad to sit on while waiting for geysers. Such a well made sturdy durable backpack. Sadly stolen in 1989. But Such good memories. Thank you kletterwerks. I trust the integrity of these folks and would buy again from them.
