I had a decades old Jandd mountaineering day pack that is just a hair too small for a serious one night outing and had no hydration options. I have been procrastinating in replacing it because it is in excellent shape, light and bombproof. But my last snow shoe hike convinced me I could not hold out any longer. If I had to guess, I would think the Jandd pack is roughly 1000-1200 cubic inches (maybe a tad bigger). This gives me enough room to pack a full set of dry clothes/thermals (compressed), food for an unexpected night's stay, first aid pouch, a selection of small survival tools/items, and my most compressible sleeping bag (all within Jandd's single compartment pack with a small top bag that acts as the cover to the main compartment's draw string opening) . I had to lash my hydration pack to the side of the day pack and went tent/bivy-less.
The Gregory pack is sized to be stuck between day pack and overnighter (or two day?). This fits my use of this bag perfectly. In the summer-time when doing easy/local/laid-back day hikes, I can take my Camelback Rogue which had just enough room for lunch, first aid, an outdoor multi-tool, and water (of course). If the summer day hike takes me beyond an easy walk back into civilization, then the Jandd seems to still work pretty good as the draw string, main compartment enclosure, accepts the Camelback bladder, and all the items I need for a summer's night out. Once you add the inclement weather of the NW (winter and some fall and spring), you need just a little bit more in terms of pack size and features as it is wise to be a bit more prepared.
The Z-30 medium is a great combination of pockets and compartments. This pack offers one main compartment with two smaller found on the top and front. The main compartment has a smaller webbed zippered pocket as well as the sleeve for the water bladder. The rain-fly has its own compartment found below the small compartment in the front and has a drain port for wet storage (a fantastic feature for the NW). I appreciate the single large compartment design as it cuts down on weight and gives me better packing options when I have unusually sized loads. The top/back of the main compartment also features two single straps with clips at the end and a sewn loop in between them. The loop is located nicely over the bladder enclosure and offers a perfect attachment for my 70oz Camelback bladder and the two clipped straps work nicely as grab locators for clothing/accessories (that are hanging the length of the pack), and organizational pouches. The clips make it possible to keep certain items obtainable without having to dig to the bottom of the main compartment. The gusseted bucket pocket is a great feature to stuff wet (as it has a drain port too!) items or shed layers quickly without having to reinvent your packing strategy. This pocket also opens wide enough to accept foot wear and more. The gussets do not continue to the bottom of the pocket leaving enough room (an inch perhaps) to allow long items with a handle or shaft to continue through the pocket for better storage placement. For example the handle of a small shovel could slide through this opening allowing for better storage/carry placement. The pack also has two very well designed lashing mechanisms that are designed to hold anything from hiking poles, tripods, and ice axes. With the bucket pocket and the two lashing features, I may have every item secured for a short climb, during the hike, where all of my extremities are required. The two webbed pockets found at the base of the pack are pleated and the elastic is quite thick and seems durable. Longer items stuck in either of these pockets can be further secured to the pack with the compression straps that are designed for the compression of the main load. Long items can be secured with both compression straps found on the side of the pack where shorter items, just breaching the pocket's brim, can be secured with just the lower compression strap. If you want the contents of these pockets to be an easy grab during the hike, the compression straps can easily miss a thermos or water bottle. This pack is full of options like the few I have mentioned. Gregory has done an excellent job incorporating storage options for the many different scenarios I will put it through. The only criticism on the storage features is aimed at the pockets found on the waist strap. They are too small for a number of things I've wanted to put in there. This is not by any means a deal-breaker nor did it drop the star-rating of this product.
The material is a great combination of durability and lightweight. The suspension and waist strap are high quality and have the same thoughtful engineering as the storage features. The lumbar pad at the base of the pack is a prominent feature should not be overlooked. If your back likes lumbar support while sitting, it may very well like this pack as much you do. I would not hesitate to also use this back for weekend traveling where hiking may be found. The bag should be of the size to qualify for carry-on during air travel.
I've noticed a couple of negative reviews online and can't help but think they are somewhat misplaced. What these negative reviews should be focusing on really should be how the design did not fit their purposes. If you bought a pick-up truck but you were a parent of 12 children, don't rant and carry on about how the manufacturer's design did not allot for all your little passengers. This is not a proper reflection on the design, production quality, or usefulness of that truck. That pick-up may very well be a terrific product, you just needed to buy a 14-passenger van. But, as it pertains to back packs, this means you will not only have to be in tune with what you really want out of a back pack, but you also have to do a bit searching and investigating in order to be in the correct style of pack - and that takes some time.
I also have used this for road biking and carry on luggage at airports.
I do not like the 2014 and recent versions of this pack. They are poorly made and cheep. I had a bad experience in the White Mountains with the 2014 z65 and the first day the shoulder strap broke. NOT GOOD!
I love this version of this pack so much that I invested in the Z65 for my multi day/extended backpacking trips/winter pack. Also make sure to find the 2009-2013 versions ( they are well worth it!) However, I am hoping that the 2016 models will be an improvement.
