Two front, exterior stretch woven pockets make it easy to tuck your windshirt or skins for swift retrieval. Side stretch woven pockets keep water bottles handy. The top lid has a zippered compartment for stashing cameras, snacks, etc. Our re-direct waist belt secures the load.

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 this bag in advance of a trip to Big Bend National Park for use as a daypack, and boy did it deliver. It's incredibly comfortable and you can get the bag dialed in just right thanks to the yoke, which can be adjusted easily using the removable, spade-like frame sheet to wedge in between the harness and the bag. Check out the videos online of Mystery Ranch's Futura system to get an idea for what the process is like. The bottom line is that it's incredibly comfortable. The thick, padded shoulder straps work great in conjunction with the sternum strap and waist belt (with padded wings) to keep the pack right where you want it. This is not a particularly light bag, but for a daypack, trading a few ounces for a lot of comfort is a decision I'd make every day and twice on Sundays.

As for the guts of the bag, Mystery Ranch's Tri-Zip is stellar. You can run the bag like a top-loader for accessing frequently-used goodies by pulling open the lid of the bag (top two zippers), or open it completely for dead-simple loading by unzipping all three zippers. It's a really clever solution that gives you the best of all worlds. The zippered stash pocket at the top of the lid is great for sunglasses and the like. Internally, there's a pouch and hanger for a hydration pouch, although it's a snug fit: my 2L Camelbak Cruz just fit when full. Pass-throughs let you route the hose out of the bag without opening any of the waterproof zippers, which is good if you're planning on getting soaked. Speaking of, the combination of 420D fabric and waterproof zippers mean this bag should stay fairly dry in the rain. The bag is 25L, which feels just right in terms of capacity for a daybag: it'll hold water, snacks, a spare layer or two, camera and goodies, and a first-aid kit and will still have some room left over.

So, long story short, I love this bag. I have only a few things to kvetch about:

The stretchy pockets on the front of the bag are great for stashing trail maps or a headlamp. The pockets on the side will each fit a 1L Nalgene, but the bottles don't feel very secure (I had one fall out when I leaned over to re-tie a boot). A synch would be helpful here, or at least an anchor point for a carabiner. The other gripe is that the bag has, essentially, zero internal storage provisions. The Mystery Ranch Urban Assault has some small but useful zippered mesh pockets on each flap of the bag (to either side of the central zipper). Those would have been helpful here.

All-in-all, though, this is a great bag by a great company. Buy it and see the difference!
I started my backpack obsession with a Dana Designs Terraplane in 1997. 20 years later my Terraplane continues to serve me well every summer and I expect the same to be true of the Coulee 25.

I have had the Coulee 25 for 6+ months and have it for every day carry to work, numerous winter/spring/summer day hikes, and international travel...this pack is a true all-arounder and carries a heavy load very well as well as compressing down for small loads.

I'd recommend this to anyone looking for a rugged, well designed bag that will last.
