In 1992 I purchased my first internal frame backpack from Great Pacific Ironworks in Santa Barbara California. A Dana ArcFlex Terraplane. The first trip I took it on was a train to Prescott AZ, where it moved me and all my belongings to college. First backpacking trip was soon after. 21 days in the Mazatzal wilderness. 70 pounds starting weight (on the back of a 22 year old kid) and the pack was amazing. I carried that pack for years through the National Forests of Oregon and California, finally loaning it to a friend in 1998... for it to show back up in my life in 2015. Well worn from my adventures and many others.
Now that I am in my late 40's with some extra weight that original Terraplane no longer fits my structure. So I looked online and found that Mystery Ranch had re-issued the Terraplane. Knowing that I had always regretted not purchasing an AstralPlane I waited on purchasing the new Terraplane. Last week I saw the T 100 had been built. Exactly the platform I have been looking for.
I received my pack a few days ago, fit and finish are exactly what I expected from a Dana Gleason product. I loaded it with a winter gear load, 6 days of food, gallon of water, water filter, etc etc etc. It carries the load just like I would expect from a Dana Gleason product. No longer being in the military I am not concerned with being Berry Compliant.
This pack is everything Mystery Ranch says it is, and more. 20+ years of additional design, build and materials experience shine through in this well built backpack. 5 Stars.

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.
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#).

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.
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 pack because I had used a Dana Design in the past that was very similar and in my opinion there isn't another pack you can carry 90 lbs comfortably with. I have no hips so I need to really torque down waist belts when I'm carrying a heavy pack and it's always been uncomfortable. I'm not sure I could ever completely eliminate that discomfort without extra padding but this is the most comfortable pack I've used, carrying the most weight I've ever carried. I was concerned I might bust the waist clip with how tight I had to make it but this pack held up for 28 days on Denali and took a fair amount of punishment. If it can make it through a trip like that, I have no concerns about taking it anywhere else. We had to bushwhack initially and after being constantly whacked with branches it never had any rips. Once on glacier, it was exposed daily to snow, ice and tools, being overstuffed with equipment. The clips, zippers, seams and fabric where all in great condition at the end of the trip. I had no doubts but thanks for making a quality product people can depend on.
Purchased the T-100 from a local dealer in Salt Lake City, UTAH recently. I just returned from an extended stay in the Utah Wilderness and I was incredibly disappointed in the T-100. After paying a premium for this bag ((which although it was made in China, Mystery Ranch guarantees that quality is same as bags manufactured in USA)) I had the main buckle on the waist-belt BREAK!!! For a moment, I just looked at it in stunned silence...I am accustomed to the incredible bags produced by this company when they went under the name of Dana Designs and they (the old bags) have NEVER failed me...straps, buckles, material, zippers, etc still work great (years after the fact), hence the reason for my complete SHOCK and DISMAY when the buckle on this bag broke (ON THE 1st USE!!!). After recovering from the SHOCK I quickly realized how incredibly F*D I was...I was miles and miles away from the truck, with a heavy pack, and 7 more days of backpacking ahead of me. Before you blame me (you had it on wrong, the strap was twisted, pack too heavy, etc) please know that I have backpacked extensively over the course of my life and as I just finished saying I have almost always used the Dana Design bags...I know what I'm doing...it was NOT user error. For those of you who backpack I know that I don't need to explain how miserable the next 7 days were without a proper functioning backpack. Suffice it to say that I am making arrangements to return this Piece of S *T bag through the local dealer. If you guys (Mystery Ranch) are going to have your gear made overseas you better make F*G certain that the quality is there...it's no joke when your bag fails on you in the wilderness. Still can't believe I paid over $400 for this piece of junk...let's see if Mystery Ranch has the guts to post this real-life review.
