Striking a balance between weight and durability, the high-performance Gregory Z35 internal frame daypack employs lightweight, high-tenacity fabrics and an innovative, streamlined suspension system to provide load-carrying capability for long day hikes or overnights in the backcountry.
Well aware of the problems that arise from ill-fitting backpacks, Gregory is committed to providing fit, comfort and load-carrying capability. This commitment is evident in the technology used in the Z35's harness and CrossFlo suspension system. A lightweight wire X-Frame and a trampoline-style backpanel work in tandem to support the stability of the Z35 by distributing weight evenly and transferring the load to the lumbar pad and waist belt. Die-cut foam on the harness and waist belt adds breathability and decreases weight. The ventilated moisture wicking harnesses, waistbelt and backpanel enhance fit, aid in load transfer, provide cushioning and keep you cool on the trail. An adjustable sternum strap and load-lifter straps further enhance the fit of the Z35 and ensure the stability of your load, allowing convenient on-the-go adjustment.
The single main compartment of the Z35 has an extendible drawstring-closed top entry, and a U-shape zippered entry allows full front access to the pack body. A huge front "bucket" pocket with mesh sides offers convenient storage for gear or wet clothes. The Z35's top pocket has a key clip and a second stash compartment on the underside. All of the zippers used on the Z35 are designed to be weather resistant.
The Z35 also includes side and bottom compression straps, quick-access waistbelt pockets, two exterior stretch water bottle pockets and hideaway gear loops. An integrated sleeve and exit port make the Z35 compatible with a hydration system (sold separately). A color-matched rain cover is also integrated.
Available in your choice of color options, the Gregory Z35 backpack is available in Medium (2136 cubic inch capacity) and Large (2258 cu in) size options.

- Great Suspension... A few flaws though
Likes: The suspension is fantastic. I can only hope the Zulu series, which replaced this line, has the same system. This pack carries extremely well. The hipbelt is angled in a way I wasn't used to and worried me a bit when I first tried it on. Loaded up with about 22 lbs. of gear for a long day hike and it carried like I barely had anything on. Great airflow too; never got sweaty hiking in about 80 degree weather. If you have a small and/or narrow hydration bladder (see dislikes) or prefer to carry water bottles, this may be a great pack for you if you do long day hikes or just like to carry extra gear on your hikes.
Dislikes: Unfortunately, unlike the suspension, I didn't care for the way the pack was organized. There are a lot of straps and zippers on this pack which at first might seem to lend to better organization but ultimately just annoyed me. There is a large J sipper to access the main compartment in addition to the top access but it was a little cumbersome. The hydration sleeve is also very narrow and couldn't fit my Osprey bladder which is a little wide. Also, because of the (fantastic) suspension, it pushes the bladder out at an angle which eats up a lot of the pack space... Not a great design if you plan to carry a water bladder like I do.
Likes: Outstanding fit for a person my size 6' - 4". Great spacing off the back also maximizes airflow. Have to have an integrated rain cover if your memory works like mine!
Dislikes: ?? So far, this meets my needs better than anything I have tried so far.
