A pack is the most important piece of gear on a backpacking trip, and I thru-hiked the Appalachian Trail with the Gregory Z55 (2010 model). This pack worked wonderfully for me.
The L-size is actually 61 liters, which fit all my gear perfectly -- sleeping bag/pillow in a compression sack went into the bottom, and it slipped right in with no problems, despite the curved frame.
The adjustable hipbelt was helpful since I, of course, lost weight on the AT. The entire hipbelt and harness system was quite comfortable on me once properly adjusted. And the suspension easily handled loads up to 40 pounds. Beyond that, there was a nice creaking with every step I took.
Most thru-hikers wear out their packs on the AT. Not so with this one. It's ready to go again.
This is a good pack, but I did find some things that I didn't like about it. I know several other people put this in their reviews as well, but the first thing I found was don't put too much weight in it or the suspension becomes uncomfortable. The second thing was also what James Jenden mentioned in his review, when you have a lot of gear in your pack you can't fit a camelback bladder. At least not without it breaking and getting your stuff wet. Other than those two things though, I do like the pack. I use it just for overnight camping trips when I don't have to carry too much stuff.
This pack does what its suppose to. What more can I say. Some friends and I went for a weekend hike and after 15 miles the only thing sore was my legs. It kept the weight off my shoulders which is what I wanted. Im 6' 2" and this pack was a little short for my torso. But it still worked well. I overpacked just to see how it would do. In the end it weighed 33.6 lbs including water, and i could carry it without discomfort. I would say it's not the best pack in its price range but it's definitely one to consider.
Solid pack for hiking with multiple people. Might be a little small if you're looking to hike solo. A bit hard to get a water bottle into the side pouch on the trail. Loads easily with three nalgene bottles across the back. The top cover/pouch is a little annoying the way it is attached by straps to the bottom portion of the pack and falls backward when opening. Just took it on a 2 day 23 mile loop in the Ouachita National Forest and it performed very well. I would recommend it without hesitation.
Ok so anything you wear on your body is objective in review I believe... I got the large size Z-55. With that said this thing fits me like a glove, I'm 6' 180lbs. The lumbar is in a perfect place for my back. its not the lightest pack I've ever owned but it fits me better, and is a well thought out design. No rain cover but I already had one so it didn't matter to me.
Mine's just slightly different, so I may have last year's, but this thing is great! I have the Large, and though I've only done 1-night trips so far, it has capacity for quite a bit more. Super comfortable; well vented; the shoulder straps made my collar bones a little sore and irritated afterwards - odd but not a huge deal...
Haven't tried it in the rain, but it sheds waterfall spray and damp cliff drips quite well.
This is a great pack. It may not be the lightest pack for its volume, but that being said it more than makes up for that in it's fit and ability to carry heavy loads comfortably. If you're looking for an ultralight pack I would skip this, but if you are looking for a light pack that can handle heavy loads and is super comfortable this is the pack for you.
This would be a great pack for 3 season weekend trips, I had to go up a size because it didn't fit my winter gear. Felt really good on my back, however with backpacks it's always subjective to the user. I like Gregory Z series more than others because they balance weight and performance very well in my opinion.
I have been using the slightly smaller 45 pack for the past 6 months and so far really like how it performs. It is built very well... strong for a pack of it's size and full of features that usually come on larger packs. To see a full video review of this pack go to:
It's a good pack. My father cannot like it any more. The color is beautiful and the belt is nice.
I took this on a 3-day trip into the Grand Canyon--nothing crazy strenuous, 2 nights at Bright Angel. Down on day 1, fool around to Ribbon Falls on day 2, out on day 3. It broke on day 2.
By broke, I mean the center aluminum stay snapped about 1/3 of the way up from the base. I carried about 40 or so pounds into the canyon (adding a few on the way to help my wife's knees), and carried between 35 and 40 on the way out. The day it snapped, I was cinching the (seemingly nice) compression system down for the day trip to the falls. I imagine the problem had something to do with the hollow nature of the stay.
I did a lot of research and tried on at least a dozen packs before settling on the Z55, and, despite its weight, the suspension seemed capable, even resilient. I needed something that could handle a few days weight plus a DSLR system (camera, extra lens, tripod, etc.--nothing too fancy). Turns out it wasn't as strong as I thought.
Bought one last August for the comfortable suspension, though I knew the poorly designed sternum strap would cause problems (as it did on my Pyr dayback). Fixed the sternum strap it so it stopped riding up, but nine months after getting the pack the cheap clip holding the sternum strap to the left shoulder strap popped off.
Ordered a new pack as a replacement but, factory fresh out of the box, found stitching in the upper back part unraveling between where the shoulder straps are sewn in. No reply to my messages to Gregory customer service, so I'm firing Gregory and switching to Osprey.
I am sorry but I must reply to another review. I read a lot of reviews for a lot of products with a recurrent theme. This entails the critical review and analysis of a product when utilizing that said product outside of the realm of its (real) intended use. Obviously we are human and like to explore creatively in many different facets, but by using my years of experience mountaineering and powers of observation I can easily note that this is not a mountaineering and or technical pack and more simply a backpacking pack. Looking at the tool attachments and and overall design of the pack, it is not engineered for a lot of technical ice tools, crampons and heavy loads at that. The pack has a wide storage capacity meaning that it is much wider in the center of the pack, making a vertical ascension and descension difficult to maintain balance. Mountaineering packs act to distribute the weight from the top to the bottom to aid in vertical ascension and maintain counterbalance with the bodies alignment. Further more this pack has no gear slings built into it and does not have the heavy duty webbing noted in most mountaineering packs built today. Why I like the Z55? Well, the big kicker for me is I love dual access in all of my packs. If I don't have it I will literally tailor one myself. Why is that important to me? Well, I really love being able to find what I need when I want it, especially when there is a more emergent situation on the horizon. Aside from the dual access I like gregory webbing straps and hip belt, they just work for me. Anatomically, I am 5'10" about 165, and this pack in a size Large fits pretty good. I tried a medium and it was slightly to small, but the large is almost too big so I am in between. Do yourself a favor though if your serious, measure using gregory's measurement guide and you should at least have a good idea where you should be, keeping in mind all torsos were not created equal. Now what I don't like about this pack is I really don't like is the front pocket and its design. Another review disliked the capacity of this pack, but I think that you have to calculate this front pouch into the 55 liters. Unfortunately when loading the front pouch and placing some unsaid items compressed between this pouch and the body of the pack it can become quite bulky and creating and unbalanced load. For this I find this pack below my standard, but this might work well for someone of a different build than myself, or of course personal preference. As for Gregory, I really like their packs and the access points which are becoming more popular with many other manufacturers.
