I purchased this for commuting on my bike to and from work. I ride roughly 25 miles roundtrip and this pack is very light, weight is nicely distributed and its off my back so my back can breath. I was using the REI Flash 22 which was great but it laid on my back and it just did not have enough room for me. I can see myself using this bag for hike which it is designed for and trace;. The rain cover is a bonus and already came in handy on my first ride.
I've used the backpack on one hike and several bicycle rides to/from work. My only criticism thus far is that there were no instructions or website links as to how to fit and adjust the backpack properly or how to use of the nifty features such as straps to hold trekking poles. It's been a bit of trial and error on that note. But, it's a high quality product and I love the ventilated back. I have chronic back pain and this pack really helped my comfort level. Finally, a backpack with decent external water bottle sleeves - yes! This is the first pack I've had that loads from the top, so I'm still getting used to that feature and finding objects stored towards the bottom of the pack. I've always had side panel backpacks before. However, it's less likely objects will fall out from a zipper that has not been full closed. I'm glad the pack came with a rain fly too.
I have used Gregory packs for many years. The Z30 is very well made with many thoughtful details like the rainfly, shove it pocket and ice axe/trekking pole straps. The hydration ports are easy to thread with a hose from a bladder. But the absolute best thing about this pack is the suspension system. It holds the weigh effortlessly and away from your back. The pack doesn't lie on your back. Air can circulate between the pack and the trampoline part of the suspension system.
I bought the Z30 as a day pack, and it's great for that. The suspension really allows for a lot of ventilation, and for a sweaty guy like me, that's a big bonus. The shove-it pocket is great for wet sandals or other gear. Just keep in mind it has drainage holes at the bottom and so it's not for small items. The pack bag tapers a lot at the bottom, and that great ventilation takes up a lot of space, both making the bag smaller and moving load further from your back. When the pack is full, the shove-it pocket doesn't have a lot of front-to-back space. When the pack and shove-it pocket is full, the vertical zip pocket on the front doesn't have a lot of space. When the pack is so full that the load fills out the bucket closure on top, the zippered pocket on top of that flap won't have much volume inside. What I'm saying is, it's not a big roomy bag. It prizes ergonomics over volume. That said... A week after I bought this I started stuffing my gear into it and realized I could do a pretty comfy overnight with it. That was back when I was carrying a 3-person tent, a self-inflating pad, and an inexpensive, high-volume sleeping bag. If you've got a one-person tent and a bag that packs down, and an inflatable pad, then an overnight isn't even tight in this bag. You could probably go a couple nights. Heck, one time I managed to fit a Bear Vault Solo in there with everything else for an overnight in Yosemite. I don't think I've ever carried more than 20 pounds in this pack, but it's always been comfortable. I really like the lumbar support, and the hip belt is very good. It has straps you can use to adjust the angle of it.
I have used this on day trips and overnight camping. I like the way it fits, and can stow a lot of gear. The only issue was the water pouch was at an odd angle when full and made getting to items on the bottom difficult.
I ended up with a Z30 after a series of day hikes in Nova Scotia where I the weather was great and I was totally comfortable with the exception of a sweaty back. Normal ventilated packs didn't do the job. This pack does a great job of letting my back breath carrying 15 pounds or so of water, snacks, binoculars, camera, clothing, first aid, and other gear for a typical day hike (I carry my wife's stuff too). Transfers weight well and doesn't pull back on my shoulders in spite of the arched frame. There are complaints that stuff in the bottom is hard to get to with a full water bladder, but the zipper goes low enough to get around this so I don't see the issue other than costing a few extra seconds. I use bottles, and unlike some day packs the compression straps don't interfere with water bottles at all. A couple of annoyances: For the 2014 model they removed the vertically zippered outside pocket that was part of the exterior of the bucket pocket, yet there are still two layers of material that could have easily been a pocket for an ounce or two of zipper. I suppose this was to save weight, but they added it right back with enormous heavy zipper pulls on the main compartments (which I will change). My only other complaint is that you have a choice of black (which absorbs heat) or bright obnoxious colors, but that seems to be the case with the current fad in Gregory and Osprey packs. Would have liked a more natural color option. IMO this is the best option for its size if you want to get rid of the sweaty back.
This was my second backpack in the past 3 years. My first pack (not to be named) wasn't as well built as this Gregory Z30. I'm 6'0" and 200 lbs so I needed a pack that would fit me comfortably. The large size in this pack did the trick. It took 2 or 3 hikes to break in the hip belts but now it fits me like a sock. My favorites about this pack would have to be the ease of access to side pockets with the pack on as well as the generous amount of space that the hip belt pockets offer. This pack also came with a rain cover which is always a plus. Great pack for day to weekend trips!
Works well for me in the large (32L) size. I'm 5'9" but have the torso of someone who is 6'2", so trying to fit packs to me can be challenging. It's slightly bigger than I generally need for a day hike, and the suspension is very overbuilt for the capacity. I suspect you could put a 50L pack on an identical frame and it would work just fine. That being said, it's quite comfortable, and I practically forget that it's there. Much of its space goes unused on a lot of my day hikes, but I like to do evening hikes with a big set of backpacking cookware to make dinner in the wilderness, and it is the perfect size for that and an extra layer. I particularly like the hipbelt pockets, they're big enough for a leatherman and headlamp in one and camera in the other.
Extremely well designed; the weight is dispersed mostly on your hips. great back ventilation. The downside or negative...is the hip pockets are not adjustable and sit too close to the back base of the hip belt. The hip belt connection is just to narrow and is the only items that looks and seems cheap. Other than that an amazing value.
This is a very nice day-pack. Very well designed and built, with nice features. I've used a BD Zippo 27L for years for 10-30 mile day-hikes, but it has a foam support only and is really sweaty in the typical CA weather. The Z30 is a bit bigger (32L in the large size) and has a nice ventilated frame. I also like the padded straps and belt. It carries a lot of gear easily and is feather-light. Well done!
