Mammut Trion Pro 35+7

Anyone had a chance to test out the new version of this pack? Hiking with gear to carrying up multipitch?

What's the "new version" you're referring to? (Have they made changes, and if so, what year did the changes go into effect?) I have the Trion Pro 50+7, purchased last spring. I use it for cragging; it's more geared toward alpine use, with ice tool holders, etc., but I like it a lot for hauling a load of trad/photography gear. (I haven't cracked into multipitch yet, so have only used it for single-pitch cragging.)

I particularly like the fact that it loads like a traditional top-loader, but has the large U-shaped zipper to open the back panel for easy access. It's the back panel (between the shoulder straps) that opens this way, so you don't have to set padded suspension system in the dirt to access the contents.

It's hydration-compatible, but only fits a 2-liter bladder. I'd prefer a 3-liter capacity, as I've gone through a full 3 liters of water on some hot, long climbing days.

The suspension system is decent. It's not super-plush like some of the heavier packs, but I've found it adequate for my needs. I haven't experienced any issues with load balancing or discomfort, though I haven't done any super-heinous approaches with it.

Andrew, from what I’ve read online about reviews, the pack pictured looks in said reviews looks different, thus I assume the current model is a relatively new release. Thanks for the feedback on the one you have!

Reply to ancient thread.

I have the old, old Mammut Trion Guide 35-7 (looks like current Trion Nordwand 38, but not the same). The frame  can NOT be removed and is pretty substantial, heavy and rigid as light frames go. As a Swiss design element, this is incomprehensible to me and I would probably NOT consider another pack from Mammut because of this ....(To what other design weirdness might the company be prone??) And that the designers  made their hip-belt removable -- but NOT THE FRAME seems like contradictory thinking: 2+2 = 6 - 3??? Moreover, removing/replacing this particular hip belt looks like a bear and not worth the effort.

A frame on a pack of this size is pointless for almost any application. Drag a mostly empty framed pack into a one-person tent vs. same pack without a frame, and advantages of frameless are obvious That scenario accounts for a substantial amount of time spent (mostly sleeping) in the field.  Which (empty) pack would you rather cram into a duffle bag for airline travel? When skiing, a frame is at best a pointless annoyance. Notice I don't mention that "serious" climbing with 40 liters of crap on the back is beyond my ability or inclination, though I've done so a fair bit with a mostly empty (and thankfully frameless ) 50L bag. Possibly/probably a frame may be desirable for truly heavy, mule-type loads but --  leaving me out of discussion almost entirely --  this  is unlikely scenario for a 35L+  pack and/or its typical use.

Otherwise, aside from being a tad heavy, this (discontinued in my version)  pack is  nice enough. I  do MUCH like and admire the beautiful, single (rather than the usual double) strap that closes the lid, and the fact that the lid is "floating"and removable, rather than sewn on and fixed. (Some manufacturers of smaller packs seem recently to favor fixed lids or even no lids, perhaps more profitable to provide?) The full-length (heavy and sturdy) zipper access to main bag is interesting, but not at all necessary, especially on such a relatively small pack.  The  current (?) Trion Nordwand looks a bit lighter. Doesn't say that frame is removable but DOES claim belt is removable. It comes in one size, which I assume, would NOT fit me. "One size fits all" is finally and definitively NOT for me at 5'11" tall.

Also, for my personal style & use, I've decided that for simple backpacking, 35+7L requires too much fuss to pack for more than one night in summer and is thus not sufficiently versatile. (Sadly, I prefer a little more volume; like 50ish).

Much as I used to dislike Osprey & find their market dominance annoying, their stuff might be the most attractive (or more attractive) to me in this category of pack currently.  Black Diamond also attractive. Presently my "favorite" pack is a 20-yr-old MEC 55L "Brio,"  ("size large"),  despite obsolete trimmings and miserly small top pocket. Brio is exceptionally, even weirdly  tall& narrow & clamps down at  its smallest  to maybe 1/3rd larger than the 37+5L Mammut. Definitely kinda bulky, yeah; but plenty of room for loaves of bread, zero-rated schlafsacken or whatever other oddities one may sometimes want /need to stuff. And its length fits my back!!

Do you fit an ICU in it with camera gear? if so, which one?
