Our iconic pack for your boldest, backpacking adventures.

The TERRAPLANE is our most revered, time-tested expedition pack. While its legacy lines are easily identifiable, it incorporates our latest material suite, new Astral Frame, five-point lumbar belt system, and fit and sizing. The core features and top-loading design stay true to the original, yet you’ll find significant advancements in construction and fit. The TERRAPLANE represents both our heritage as well as our latest Load Carriage™ vision.

  • The Astral Frame is a robust frame that supports large loads. The mainframe is comprised of four vertical, composit stays, dense foam for flexibility and for tortional rigidity. Through patented features and construction methods, the mainframe transfers the weight of the load into the wings which relay the weight and equalizes the contact around and into the belt. The waist belt cants and conforms over the hips to effectively transfer and distribute the weight and eliminate slippage down over the hips.
  • The patented Futura Yoke easily micro adjusts to the torso length allowing the proper amount of stand-off between the back and frame.
  • Top-loading design for easy/secure packing
  • Convertible Daypack Lid feature
  • Side zip for easy access to main bag without unpacking
  • Two, exterior vertical long pockets
  • Water bottle pockets 
  • Tool carry attachment between back, vertical torpedo pockets
  • Cross compression with buckle release for accessing side zips
  • Hydration reservoir compatible
  • Five-point lumbar belt system
  • Built on the NEW Astral Frame
  • 500D Lite Plus CORDURA® fabric
  • YKK® zippers

23 Years and Still Kicking


I've got one from ~ 23 years ago, countless hundreds of miles, multiple continents, and many, many summits on it. It refuses to die - I'd like to buy a new one but I don't need one cause I already have one.

Do it!


Does not get any better than Mystery Ranch, Love this pack!

My favourite heavy hauler


I’ve had this pack for 2 years now. It is my go to pack when heavy loads are anticipated. The suspension is excellent and the pack has carried some massive loads out of some seriously steep rugged country. The construction of this pack is meticulous and so far bombproof. I don’t like to give product reviews till I’ve had a chance to thoroughly test them. The staff at Rampart International, the Canadian distributor, were helpful in getting the correct belt and yoke size for my build. 2 years in and the pack is going strong with no issues. Judging from its current condition I expect to get many more years of service from it. I own several Mystery Ranch packs and all of them are extremely durable well made packs.

Bad weight transfer and QC


-great pack bag.
-I could not get the pack to effectively transfer weight to my hips. Kept sliding down as others have mentioned. Waistbelt just did not work.
-bad quality. I was shocked to see numerous stitching errors, loose threads, and misrouted shoulder straps on BOTH packs I tried (ordered a second because I thought the first had to be a ringer). In addition, the hipbelt on the second had an obvious and major deformity in the foam. It is made in the Philippines. My Mystery Ranch stuff made in Vietnam is of great quality.
-lazy design. No hipbelt pockets, no key clip in the lid, not even an ice axe keeper like the Glacier has. Come on guys. It says it’s hydration compatible but there is no sleeve for a bladder. I actually liked the simple design but you need to add a few things and fix the QC issues.

Timeless packs


In the fall of 1992, after wrapping up my first season on a hotshot crew, I used a chunk of my hard earned money to buy a Terraplane. For years it went with me on climbing expeditions to Pakistan, Patagonia, Ecuador and all over the western U.S. in between fire seasons. I'm now a middle aged attorney, and used that same pack last weekend (in July of 2016) on a climbing trip deep in the San Juans. I was thinking it is perhaps time for a replacement (though honestly I'm not sure it actually needs to be replaced and will probably be given to one of my kids) and was wondering what happened to the original Terraplane- so happy to see it is again available!
