    Built to stay dry and cool.

    Lightweight durability and a breathable suspension system give the Gregory Z 55 Backpack the edge over other packs that claim to perform great in warmer climates. But, with a removable top lid and multiple compression options, the Z 55 works well any time of year, for alpine climbing as well as weekend trips to the local state park.

    With a maximum load recommendation of 40 pounds, the Z 55 is perfect for everything from overnighters to extended weekend hikes. Gregory's CrossFlo suspension system is strong, simple, and lightweight. It also provides cooling airflow across your back to pull moisture and heat away. At the heart of the system is the wire X-Frame, which provides effective load transfer straight to your lumbar region and padded waist belt, where it can be carried most efficiently. The dynamic Yoke integrates the shoulder harness directly into the X-Frame, activating the suspension as the weight increases to balance the frame's flexibility. The back panel is made with a moisture-wicking, breathable mesh to transfer heat and moisture away from your body.

    Access to the Z 55's main compartment is made easy with a large, u-shaped zippered opening. A large zippered front pocket provides convenient storage for items that you'll need to get to through the course of your hike, such as lunch and rain gear. The pack also provides easy access to small items with dual waist belt pockets and a large dump pocket on the front of the pack, as well as a highly water-resistant top pocket with a waterproof zipper and sealed seams. And, speaking of waterproof, the Z 55 comes with an integrated, color-matched rain cover to keep your gear safe and dry when an unexpected storm pops up.

    Z pack is fine

    • Familiarity: I've put it through the wringer

    Before you purchase this backpack make sure you know what you want to use a backpack for. If you are a specialized backpacker or hiker this might not be the best pack for you. That said this pack has worked great for me.

    Also if you are not backpacking this pack is too much pack with too few features. The lack of a bladder and the size make it a terrible pack for people who just want a large pack for dayhikes. Also, if you are only driving in to a campsite this is too much pack, just get a duffel bag to throw in the tent instead of this bag.

    I have carried this pack to the moon and back. Okay, not literally, but it has accompanied me for nearly 50 nights of camping, backpacking, hitch hiking, skiing, and any other adventure I was too cheap to buy a specialized pack for. This is a great do everything pack.

    The zipper that accesses the main compartment is great for getting into your stuff without going through the top to mess everything up. The only problem is that it is hard to access if you have other stuff strapped onto your pack.

    I have a cheap sleeping bag, which is somewhat large. I also have a large cheap sleeping pad. They are very difficult to strap onto this backpack. If you have nice stuff that packs down tiny you are probably good, but if you carry archaic but still functioning stuff like I do, you could face the same issues.

    All in all, I have enjoyed this pack, but with hindsight being 20/20 I would purchase other bags before I purchased this bag.

    Big improvement...kinda

    • Familiarity: I've put it through the wringer

    I used this pack for 300 miles of backpacking the AT from Gorham, NH to Katahdin and was previously using the past model.

    The good: the new frame design works better and is lighter. The straps and pockets have all been streamlined and improved. They added quick release buckles to the bottom straps which makes it way easier to strap a sleeping pad there.

    The Bad: They eliminated the lower side compression straps which makes it harder or impossible to strap skis or snowshoes to the pack.

    The Ugly: There isn't enough padding on the lumbar pad where all the weight is supported! I have a bony back and this started out as slightly uncomfortable but resulted in infected sores on my back after a week. I checked a bunch of other packs and found that they had at least double the padding in that area. I luckily solved the problem by cutting a square from my sleeping pad and tying it to the pack in that area.

    In all, it's hard to recommend the pack because of this one issue which sucks since they made so many great improvements.
