Gregory Zulu 24 Daypack vs EXPED Skyline 20 Daypack

Comfort is the foundation of any successful hike, determining whether you enjoy the trail or spend the day fighting fatigue. For daypacks, this means the shoulder straps, hip belt, and back panel must work together to distribute weight evenly without causing hot spots or chafing. The Gregory Zulu 24 takes the lead here with a 4.8/5 rating, driven by buyers who describe the fit as feeling like a glove and note that the free float suspension system allows them to barely notice the pack is on their back. Its contoured hip belt and breathable padding are frequently cited as key factors in its superior comfort. The EXPED Skyline 20 follows closely with a 4.6/5 rating, praised for its ergonomic airflow back system and natural range of motion, though it has slightly fewer mentions of the 'invisible' comfort found in the Zulu. If you prioritize a suspension system that feels seamless and supportive over long distances, the Zulu 24 is the stronger choice.

Durability dictates how well a pack withstands the abrasion of rocks, branches, and repeated use over the years. Buyers look for high-denier fabrics and robust construction that can handle rough terrain without tearing or fraying. Both packs receive similar, moderate scores in this category, with the Gregory Zulu 24 at 3.9/5 and the EXPED Skyline 20 at 3.8/5. The Zulu 24 utilizes RIT stop nylon and quality materials that users expect will last just as long as previous models, while the Skyline 20 relies on durable recycled polyester fabric and an integrated rain cover for protection. Neither pack has overwhelming praise for extreme ruggedness, and both have limited feedback regarding long-term wear on harsh trails. Given the nearly identical scores and the lack of significant negative feedback for either, this category is effectively a tie, suggesting both are suitable for standard day hiking but may require care on very technical terrain.

Effective ventilation is critical for keeping your back cool and dry, especially during strenuous climbs or in warm weather. A well-designed back panel prevents sweat buildup, which can lead to discomfort and chafing. The Gregory Zulu 24 is the clear winner in this category with a 4.6/5 rating, featuring a VaporSpan ventilated back panel that users describe as having 'awesome ventilation' and 'tons of breathability.' Many hikers specifically mention that even when they sweat heavily, the air speed ventilation system works effectively to keep them cool. The EXPED Skyline 20 offers a solid 4.1/5 rating with its ergonomic airflow back system and spring back mesh, which keeps the back cool during physical activities. However, the volume of positive feedback for the Zulu 24 is significantly higher, making it the superior option for hikers who run hot or tackle steep, warm trails.

Good organization allows hikers to access essentials like snacks, maps, and water bottles quickly without stopping to unpack the main compartment. Both packs excel in this area, earning identical 4.7/5 ratings from users who appreciate thoughtful pocket placement. The Gregory Zulu 24 features clean, simplistic features including an internal hydration sleeve, deep side mesh pockets, and a U-shaped front zipper panel that provides easy access to gear. Similarly, the EXPED Skyline 20 is lauded for its side-running zipper, front stretch pocket, and multiple mesh pockets all around the pack, including specific tool loops and bungees. Whether you prefer the Zulu's structured compartments or the Skyline's stretchy, accessible pockets, both designs ensure that your gear is secure and within reach. This category is a tie, as both packs offer comprehensive storage solutions that cater to different organizational preferences.

Stability ensures that the pack moves with your body rather than shifting around, which is crucial for maintaining balance on uneven terrain. A stable pack keeps the load close to your center of gravity, reducing strain on your back and shoulders. The Gregory Zulu 24 leads with a 4.1/5 rating, supported by its supportive frame, perimeter frame, and free float suspension system that moves dynamically with your hips. Users note that the load is stabilized near the body, providing a secure feel even when the pack is fully loaded. The EXPED Skyline 20 scores a 3.9/5, utilizing a spring steel U frame and a stowable hip belt to create a slim, balanced profile. While the Skyline offers a secure fit, the Zulu's more robust suspension system and frame design provide a noticeable advantage in handling heavier loads and maintaining stability on technical trails.

Adjustability is key to ensuring a pack fits your unique torso length and body shape, preventing discomfort and inefficient weight distribution. A pack that cannot be adjusted properly may ride too high or too low, causing strain regardless of its other features. The EXPED Skyline 20 wins this category with a 3.9/5 rating, offering adjustable load control straps and an adjustable harness that allow for a more customized fit. In contrast, the Gregory Zulu 24 scores a lower 3.3/5, as it is often described as a 'one-size-fits-most' design with limited torso adjustment options. While the Zulu does offer two torso size options, some users report that the shoulder straps can end up being too long or that the fit isn't perfect for all body types. If you have a non-standard torso length or require precise fit adjustments, the Skyline 20 is the more versatile choice.
