Gregory Zulu 24 Daypack vs REI Co-op Traverse 35 Daypack

Comfort is the foundation of any hiking experience, determining whether a pack feels like a burden or a seamless extension of your body. For buyers, a high comfort rating means the suspension system effectively distributes weight without causing hot spots or pressure points on the shoulders and hips. The Gregory Zulu 24 stands out here with a 4.8/5 rating, praised for its free float suspension system and contoured hip belt that cradles the hips, making it feel like you don't even notice you're wearing it. While the REI Co-op Traverse 35 also scores well at 4.4/5 with strong hip support and padded straps, some users with smaller waists found it less soft than other options. Ultimately, the Zulu 24 offers a slight edge for those seeking an immediate, glove-like fit, whereas the Traverse 35 provides solid comfort that may require more fine-tuning.

Durability dictates how well a pack withstands the abrasion of rocks, branches, and repeated use over the years. Buyers look for robust materials like ripstop nylon and reinforced stitching to ensure their gear stays protected. Both packs receive similar ratings, with the Gregory Zulu 24 at 3.9/5 and the REI Co-op Traverse 35 at 3.8/5, indicating that neither is significantly more rugged than the other. The Zulu 24 utilizes RIT stop nylon that users feel will last just as long as previous models, while the Traverse 35 features water-resistant construction and dense mesh that has held up well over a decade of use for some. Although the Traverse 35 has more mixed feedback regarding wear holes and loosening straps, the Gregory's limited data points suggest a similar level of reliability for standard trail use.

Effective ventilation is critical for preventing sweat buildup and keeping the back cool during strenuous climbs or hot weather hikes. A superior back panel design allows air to flow freely between the pack and the wearer, significantly improving comfort on long days. Both the Gregory Zulu 24 and the REI Co-op Traverse 35 achieve an impressive 4.6/5 rating in this category, proving they are equally effective at managing heat. The Zulu 24 utilizes a VaporSpan ventilated back panel with specialized mesh that users describe as having excellent breathability, while the Traverse 35 relies on a suspended air-mesh design with channels cut for heat dispersal. Whether you choose the Zulu's open-air system or the Traverse's mesh channels, you can expect a dry back and significant airflow on both packs.

Organization determines how easily you can access essentials like water, snacks, and navigation tools without stopping to unpack your entire bag. A well-organized pack features a logical layout of pockets, compression straps, and dedicated sleeves for hydration bladders. The REI Co-op Traverse 35 dominates this category with a 4.9/5 rating, offering an overwhelming array of storage options including hip strap pouches, a top administrative pocket, and multiple compression points to secure gear. The Gregory Zulu 24 is also highly rated at 4.7/5, praised for its clean, simplistic features and deep side mesh pockets that keep essentials accessible. While the Zulu 24 is perfect for those who prefer a streamlined approach, the Traverse 35 is the clear winner for hikers who need to carry and organize a larger volume of diverse gear.

Stability ensures that the load remains close to your center of gravity, preventing the pack from swaying or bouncing as you move over uneven terrain. A stable pack uses compression straps, frame sheets, and load lifter straps to cinch the gear tightly against the body. The REI Co-op Traverse 35 excels here with a 4.6/5 rating, utilizing a spring steel frame and robust cinch mechanisms that users say eliminate flopping and keep the bag secure. The Gregory Zulu 24 scores a 4.1/5, offering a supportive perimeter frame and side compression straps that provide good stability, though it lacks the aggressive cinching of the Traverse. For technical terrain where every ounce of movement matters, the Traverse 35's ability to lock the load in place gives it a distinct advantage over the more relaxed suspension of the Zulu 24.

Adjustability is crucial for ensuring a pack fits a wide range of body types, allowing users to customize the torso length and strap positions for a perfect fit. A highly adjustable pack can accommodate different shoulder widths and hip sizes, reducing the risk of discomfort or injury. The REI Co-op Traverse 35 is the undisputed leader with a 4.8/5 rating, featuring extensive cinch points, adjustable sternum straps, and movable attachment loops that let users fine-tune the fit precisely. In contrast, the Gregory Zulu 24 scores a lower 3.3/5, as it is designed as a one-size-fits-most option with limited torso adjustment, which some users found resulted in shoulder straps that were too long. If you have a non-standard body shape or need a highly personalized fit, the Traverse 35 is the superior choice, while the Zulu 24 works best for those within its standard size range.
