A durable, versatile classic

In 1990 I bought a Dana Design Terraplane and Feathered Friends sleeping bag for a winter mountaineering trip in the Colorado Rockies. Until 2022, I had both, but I gave the Terraplane away when I moved internationally. After 30 years, it still had a lot of life in it! I used that backpack for multiple backcountry ski mountaineering trips in the Rockies as well as travel in the Canadian wilderness, Africa, Nepal and 2 years backpacking in Southeast Asia. I had a compatible Dana Design duffle that worked really well to cover the pack for international flights, and it also took the grease stains from rickety old boats and busses in SE Asia, keeping the backpack in good condition. Over those 30 years, the only thing that needed replacing was the foam pad which broke down to years of exposure to sweat and the elements. The pack comfortably carried everything I needed for winter trips. Over the decades, I wondered if a more modern, lighter backpack would be better, as the Terraplane always felt a bit heavy / burly--but that's probably why it lasted decades. The other issue I didn't like was that the lid compartment was large and would flop around unless totally filled. A minor issue was that the OG version didn't have a quick access to the length of the main compartment. Bear in mind, these comments are not for this updated version. Now I'm back in the market to replace it, and I see that the bag is back in production. Surprisingly, the weight difference between it and some other options isn't that much. I'm inclined to get the new Terraplane because it's such a good bag, though now that I'm older, it's probably overkill for me. Adjusted for inflation, it's cheaper now than back in 1990, and if the new version is as good as the older one, it will no doubt last me the rest of my life. I've attached photos of my original Terraplane as a testament to how well it held up. Sorry if this review isn't entirely relevant, but I saw a few other OG Terraplane reviews, so I thought I'd add my own.

Carries heavy loads well

Bought this a few weeks ago for a backpacking trip with my kids since I knew I would be carrying more than my fair share of the gear. This pack carried the load really well even stuffed to the brim and with items strapped to the webbing.

Haul everything

Bought this and took it on a trekking trip in Iceland. Multiple days across 40 miles of mountains valleys, the pack perform very well. The storage for a sleeping bag on the bottom is great. Very simplistic and functional concept. That makes it easy to steal your bed roll. I imagine the two outer tube style zipper pouches would also do very well if you were backpacking out meat after a hunt.

Recently purchased for extended backpacking excursions. Concerned about hook and loop longevity due to the taking out the yoke every time to use hood for daypack. Use of the main pack shoulder straps are overkill when used with small and non-ergonomic to the back hood for day hikes from base camp. Seems the older waist pack version is a more practical, durable and capable design. Thinking of sewing on waist straps for waist pack/fanny pack use. Is this something Mystery Ranch can do?

Well built

Tried it out and works well. I will use this spring/summer/fall in the Sierras.

Seems great

I bought this to replace my decades-old Dana Design. I haven't had a chance to take it out on the trail but the features seem great and same basic design. It's also much lighter weight than my old one. Looking forward to logging some miles!

Revisions needed

I bought the Terraplane to replace my original Dana Terraplane from 1995. A couple of issues though. The 2 section top pocket is a waste of space and added weight. I never know where I put anything up there in the 2 small pockets and it won't take a map unless it's folded up small. The one pocket top pocket as on the original is more functional. The sleeping bag compartment seems much smaller than the original Terraplane. The buckle system on the sleeping bag compartment is just more weight and will wear more rapidly. Seems good for carrying weight but the 2 mentioned downfalls are a definite minus.

A near identical replacement for my 1994 Terraplan

This new Terraplane is a near identical replacement for my much loved 1994 Terraplane that served me well all over the world for nearly 30 years. The new M. R. Terraplane has some smart upgrades and keeps the DNA of the old versions. The waist belt and shoulder yoke are big upgrades in comfort and fitting. It took a little bit to fit the pack to me but once I got it adjusted it fits like a glove. I'm looking forward to another 30 years out of this pack. The only reason I'm giving it 4 stars instead of 5 is that I'll need several years to judge it's long term durability. It's got big shoes to fill.

Since 1996

I got the Dana Designs (now Mystery Ranch) Terraplain backpack in 1996. It is by far the very best pack I have ever owned. I hiked across the Olympic mountains for 11 days on a very rugged route. Half of the trek was cross country with no trail. I started with 80 pounds but it felt lighter. It was an epic trip and the Terraplain pack made all the difference. It was High Divide trail, Bailey Range Traverse, Skyline Route, North Fork Quinault rainforest trail.

Awesome heir to the original Dana Pack

I bought this pack with tears in my eyes after my original Dana Terraplane that I purchased prior to my AT thru hike in 1995. (Frodo '95) I must have put close to 10,000 subsiquent miles on that pack and it served me well. This pack fit me fantastic out of the box as I thought that it would. The hip belt is more cuhy-er if that is a word? I put a moderate 40 pound load onto it and it felt great! The load transfer right to my hips were great as I have a disc problem in my neck (old age sucks). A four-day circuit close to home in the Catskills and the new pack is off to a fantastic start. I doubt that I will ever come close to doing what the original put on however this new pack is fantastic. The new water bottle pockets are certainly welcome. I don't have to beg the wife to sew our own. Good job guys!
