Warmth

4.9/ 5.0

Warmth is a critical factor for any down jacket, especially for hiking in cold conditions. A warmer jacket ensures that you stay comfortable and safe in low temperatures, allowing you to focus on your hike without worrying about the cold. The Outdoor Vitals Zulu Down Jacket stands out in this category with its 900 fill power down, providing exceptional warmth and heat retention. It is praised for being incredibly warm, with high loft and efficient thermal rating, making it the warmest jacket for its weight. The Mammut Broad Peak IN Hooded Jacket, while still warm, is slightly less warm than some premium competitors. It offers excellent warmth with high-fill down and wind-resistant fabric, but it may not be as warm as the Outdoor Vitals option.

Fit

The fit of a down jacket is essential for both comfort and functionality. A well-fitting jacket will keep you warm without restricting your movement, and it should also allow for layering if needed. The Outdoor Vitals Zulu Down Jacket offers a better fit with a somewhat trim silhouette and a scuba-style hood that provides good heat retention on the head. It also features elasticized face openings and adequate arm length, making it comfortable and functional. The Mammut Broad Peak IN Hooded Jacket, while offering a secure fit with elasticated hood and cuffs, can be a bit snug, especially when layering. This might be a consideration if you plan on wearing multiple layers underneath.

Durability

4.8/ 5.0

Durability is crucial for a down jacket, as it needs to withstand the rigors of the trail and last for many seasons. A durable jacket will save you money in the long run and ensure that you stay protected in harsh conditions. The Outdoor Vitals Zulu Down Jacket excels in durability with its 15D nylon zero stitch fabric, which is tightly woven and downproof. It is praised for its resilience and ability to bounce back, making it a burly durable puffy jacket. The Mammut Broad Peak IN Hooded Jacket, while durable with its abrasion-resistant Pertex Quantum fabric, has some minor issues like loose threads. It holds up well to rough use but may not be as robust as the Outdoor Vitals option.

Comfort is key for any piece of outdoor gear, and a comfortable down jacket will make your hiking experience much more enjoyable. Both the Mammut Broad Peak IN Hooded Jacket and the Outdoor Vitals Zulu Down Jacket offer high levels of comfort. The Mammut jacket features a plush and squishy fabric with microfleece on the inside and smooth zippers, making it cozy and comfortable against the skin. The Outdoor Vitals jacket is praised for its softer, luxury feeling, and really malleable fabric, providing great coverage and breathability. Both jackets are comfortable and well-built, making this category a tie.

Packability is important for hikers who need to save space in their backpacks. A packable jacket can be easily stowed away when not in use, making it convenient to carry. The Mammut Broad Peak IN Hooded Jacket is extremely compressible and lightweight, easily stuffing into its own pocket for compact storage. It is praised for being super compressible and the most packable, making it ideal for those who prioritize saving space. The Outdoor Vitals Zulu Down Jacket, while packable, is not as compressible as the Mammut option. It packs down reasonably well but may not be the most compact choice.

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 easier to climb, scramble, and hike. The Mammut Broad Peak IN Hooded Jacket is designed for active use, offering good mobility with features like thumb hooks and harness-compatible pockets. It is praised for being nice for climbing and squatting types, making it a great choice for those who need to move around a lot. The Outdoor Vitals Zulu Down Jacket, while comfortable, has limited mobility due to its snug fit. It is more suited for static use and may not be as ideal for active pursuits.
