Warmth

4.9/ 5.0

Warmth is a critical factor for down jackets, especially for hiking in cold conditions. A jacket with superior warmth will keep you comfortable and safe in low temperatures, making it a key consideration for winter hikes or high-altitude treks. The Outdoor Vitals Zulu Down Jacket stands out with its 900-fill down, which provides exceptional warmth and heat retention. Buyers consistently praise its warmth, noting that it is incredibly warm and efficient in cold temperatures. The Rab Neutrino Pro, while also warm with its 800-fill hydrophobic down, doesn't quite match the Zulu's level of insulation. If you prioritize warmth above all else, the Zulu is the clear winner.

Fit

A good fit ensures comfort and mobility, which are essential for a pleasant hiking experience. A well-fitting jacket allows for layering and freedom of movement, making it versatile for various activities. Both the Rab Neutrino Pro and the Outdoor Vitals Zulu offer a good fit, but they cater to slightly different preferences. The Neutrino Pro has a regular fit with articulated sleeves, providing plenty of room for layering and freedom of movement. The Zulu, on the other hand, has a somewhat trim silhouette with a scuba-style hood, offering a good fit with adjustments to trap heat inside. This category is a tie as both jackets excel in fit but cater to different needs.

Durability

4.8/ 5.0

Durability is crucial for hiking jackets as they need to withstand rough terrain, abrasion, and various weather conditions. A durable jacket will last longer and provide better value for money. Both the Rab Neutrino Pro and the Outdoor Vitals Zulu are highly durable. The Neutrino Pro features Pertex Quantum Pro ripstop nylon and a PFC-free DWR finish, making it resistant to wind, water, and abrasion. The Zulu, with its 15D nylon zero stitch fabric and tightly woven fabric, offers exceptional durability and resistance to dirt, wind, and dust. Both jackets are built to last, making this category a tie.

Comfort

Comfort is essential for any hiking jacket, as it directly impacts your overall experience on the trail. A comfortable jacket will feel good against your skin, allow for easy movement, and keep you cozy in various conditions. The Outdoor Vitals Zulu Down Jacket is praised for its softer, luxury feeling, and really malleable fabric, providing a high level of comfort. The Rab Neutrino Pro is also comfortable, with a cozy fit and soft fabric, but it doesn't quite match the Zulu's level of comfort. If comfort is a top priority, the Zulu is the better choice.

Packability

Packability is important for hikers who need to save space in their backpacks. A jacket that packs down small is easier to carry and store, making it more convenient for long hikes. The Rab Neutrino Pro excels in this category, as it is easily compressible and packs down surprisingly small. It can even be stuffed into its own pocket, making it very convenient to carry. The Zulu, while also packable, doesn't compress as small as the Neutrino Pro. If you need a jacket that is easy to pack and carry, the Neutrino Pro is the clear winner.

Mobility

3.0/ 5.0

Mobility is crucial for active hikers who need to move freely and comfortably. A jacket with good mobility will allow for a full range of motion, making it suitable for activities like climbing or scrambling. The Rab Neutrino Pro offers better mobility with its articulated arms and adjustable cuffs, hem, and hood, allowing for unrestricted movement. The Zulu, while offering some mobility, is more suited for static use due to its snug fit. If you need a jacket for active use, the Neutrino Pro is the better choice.
