Mammut Trion Tour 28+7L Backpack

A classic alpine pack for fast and light ascents.

Load up everything you need for an afternoon at the crag or a day in the alpine in the Mammut Trion Tour 28 Plus 7 Backpack. This well-rounded pack is great for fast and light ascents or mellow days at the crag thanks to its close-fitting cut and array of climbing-specific features. In addition to its height-adjustable lid with two zippered pockets, the front of the pack is also fitted with ice axe loops, daisy chain gear carriers, and a rope fixing strap under the top lid. A hydration system compatible design allows you to stay properly hydrated during the approach, while padding at the back, hips, and shoulders ensures the pack stays comfortable while you mob back to the car after another successful summit bid.

Good looking bag, too tall for long-haul

  • Familiarity: I've used it several times

I really like the look of this bag ( got the smoke)and you can stuff a lot of things into it because the top extends a fair amount—shoes, clothes, lunch, rope, helmet—but it just didn't fit right. I wear a medium in Osprey packs, or a M/L in their less technical packs, but this Mammut bag was too tall for me. If I wore it comfortably on my shoulders, the hip belt would be too low, and if I hoisted it up so the hip belt sat correctly, the bag would hit me in the back of the head. I still use it when I can pull the car right up to the crag, but backcountry pursuits would be too uncomfortable.

The limited accessibility and features (as noted by the other reviewer) also really bug me. You pretty much need to dump the entire bag every time you want something.

Excellent construction, lacks features

    This pack is lightweight and very solidly put together. The adjustable components provide a well adapted and minimally encumbering fit. However, I failed to take into account the inconvenience of a total lack of accessory compartments or alternate points of access (top only). If you only expect to get into the bag in relaxed times, not a problem. But semi-frequent changes of layers, snacks, etc are a chore.

    Can the lid of this pack be removed?

    I am having trouble deciding between this pack and the Trion Light 28. What are the differences? How is the expansion (the +7) handled?

    Best Answer

    Hi Aaron,



    The lid on this pack is not removable. The lid is where the expansion (+7) is handled. You would extend the sleeve at the top of the pack and fill it up, then extend the lid over the top and tighten it down with the attached compression straps.
