Should have bought 2

  • Familiarity: I've put it through the wringer

Admittedly, I whimsically purchased this pack before a snow-camping trip on Rainier. Since then I haven?t needed a pack for anything else since it?s loaded with the right features, yet remains simple: Winter camping loaded with Bandit/Rainier? 7-day Summer hike? Summer skiing? Carry-on travel bag (remove hip belt)? And now, slowly, Alpine climbing?


'I've put it through the wringer' is ironic in that by the time you can give a product that backing, it's no longer available to others. (~1530g w/ all buckles and untrimmed)

Unanswered Question

Does Mammut offer different size hip belts for the Trion Guide?

Superior Pack

Out of all the packs I have owned and used this pack by Mammut supersedes the rest. Black diamond, Gregory etc. are great packs but Mammut excels them through quality, workmanship, and functionality. Either going up Mt. Shasta or to Nepal this is the pack I will take.

Great trad climbing pack

  • Gender: Male
  • Familiarity: I've put it through the wringer

I've use this pack at least 2x/week for almost two years and it as my only climbing pack. I previously had a Gregory z-55. The Gregory carried my rack slightly more comfortably but slithering up against granite tore it to shreads in just a few months. This pack has a few small holes, but they don't go through both layers of the pack. I carry full rack from Mastercam 000 sometimes up to BD #6 with doubles of .5 to 3, harness, shoes, helmet, extra jacket, alpine draws and quick draws, food, 2or 3 32oz Nalgene bottles of water, guidebook. The pack carries this easily. I make my partner carry our rope. If we need doubles, this pack has a great system for securing rope on outside of pack. Pack also has exterior pocket on front and a removable/adjustable pocket on top with separate interior and exterior compartment. I'll probably use this for another 2 or three years or until it rips through both layers. One of my buds liked mine so much he bought one. Mine just looks better because its been put through the wringer. Mammut currently makes the best ropes and packs in my opinion and the elephant looks cool

Great pack, comfortable for long hikes

I've been using this pack for well over a year. I'm a rock climber, so I've primarily been using it for that (although it has plenty of features for ice climbers, skiers, etc...). I've often filled this thing with TONS of heavy gear and have walked for a long time in it--and it's proven to be extremely comfortable, even under seriously heavy loads.The fabric has a cool, almost rubbery coating in certain places, making it super rugged.

Great pack, lots of uses

This is an excellent pack, useful for everything from multiple night backpacking trips, backcountry skiing, ski mountaineering, and day hikes. This is an excellent update from last year's version, including a larger and better crampon/outside pocket, new optional side straps at the bottom of the pack, a larger side access zipper, more useful ice axes loops, and other small fix-its.

The butterfly motion mechanism is comfortable, especially with a larger load. It doesn't sway side to side, just allowing the pack to stay relatively centered especially when you are scrambling, climbing, or making other drastic, body-shifting moves. It carries a pair of skis/splitboard really comfortably and doesn't block quick access to the pack. You can remove the hipbelt for day hikes.

It doesn't have the best back ventilation, nor are the shoulder straps the most comfortable out there, but it's an extremely durable pack with tons of versatility.

Does the butterfly frame make enough of a...

Does the butterfly frame make enough of a difference to push pack decision one way or another if the pack carries the weight well anway? My previous packs only used a simple plastic framesheet so I used to not think too much about suspension until I tried the BD system and was blown away. I'm torn between the mammut trion guide 45 or the rei pinnacle 50 which I can get for about half the cost.

Responded on

This is going to be a much higher quality pack. I've used many different packs, these are top tier. Here is some good info about the frames that Mammut uses.

Responded on

I know this answer is coming a little late but I can't resist the chance to tout the Motion Butterfy suspension system. It is one of the features that makes the Trion series so great but it is especially evident in the lighter packs from Mammut. The Trion Light for example carries a lot of weight very comfortably which is not always the case with super light alpine packs. This suspension system has really made the difference for me.

Bomber pack!

Great update to the previous Trion Guide. Front Pocket redesign is killer. You can now fit much more in the front pocket even carry most standard shovels so use as a ski pack makes this a year round tool in the quiver. New Ice Axe attachments also will work with any type of axe now. Full side zip access on one side is great and love the rope carry strap under the lid for when you got this baby maxed with gear and can't fit your rope inside. Super tough 420 Triton ripstop and Balistics base and reinforcements will ensure this pack holds up. Molded belt and back panel and the butterfly frame make this thing carry and climb like a dream.
