4.4/ 5.0

Warmth is a crucial factor for fleece jackets, especially when hiking in cool or cold conditions. A warmer fleece can make a significant difference in maintaining comfort and performance on the trail. The Arc'teryx Kyanite Hoody Women's excels in this category, offering a nice warm piece that performs well in cold conditions and is suitable for layering under a shell in colder environments. It provides a ton of wind resistance and keeps your core warm, making it a solid choice for winter sports and cold weather situations. The Mountain Hardwear Summit Grid™ Hoody also retains heat well and keeps you dry, but it may not be as warm as the Kyanite Hoody in really cold environments. Therefore, if warmth is your top priority, the Kyanite Hoody is the better option.

Comfort

4.8/ 5.0

Comfort is essential for any fleece jacket, as it directly impacts your overall hiking experience. A comfortable fleece moves with your body, feels soft against the skin, and doesn't cause irritation. The Arc'teryx Kyanite Hoody Women's stands out in this category with its super soft fleece, buttery smooth texture, and comfortable fit that doesn't feel tight. It is praised for being incredibly soft and cozy against the skin, making it a versatile and comfortable choice for all-day wear. The Mountain Hardwear Summit Grid™ Hoody is also comfortable and form-fitting, but it doesn't quite match the level of comfort provided by the Kyanite Hoody. For those seeking the ultimate in comfort, the Kyanite Hoody is the clear winner.

Durability

4.4/ 5.0

Durability is important for fleece jackets, as it ensures the jacket can withstand the rigors of outdoor activities and frequent washing. A durable fleece maintains its quality and performance over time, providing long-term value. The Arc'teryx Kyanite Hoody Women's excels in durability with its quality construction and materials that resist pilling and snagging. It holds up well to repeated washes and maintains its fluffiness and overall quality. The Mountain Hardwear Summit Grid™ Hoody also holds up to regular washing but may not be as durable in the long term with heavy outdoor use. Therefore, if durability is a key concern, the Kyanite Hoody is the better choice.

Fit

4.6/ 5.0

Fit is a critical aspect of any fleece jacket, as it affects both comfort and functionality. A well-fitting fleece allows for easy layering, freedom of movement, and overall comfort. The Arc'teryx Kyanite Hoody Women's offers a relaxed fit that is easy to layer and doesn't feel restrictive. It has a low-profile hood that fits comfortably under a helmet and a snug but not restrictive fit. The Mountain Hardwear Summit Grid™ Hoody also offers a comfortable fit with adjustable drawstrings, but some users may find the sleeve length slightly short. Overall, the Kyanite Hoody provides a more consistent and comfortable fit, making it the winner in this category.

Breathability

4.3/ 5.0

Breathability is crucial for fleece jackets, especially during high-output activities where moisture management is key. A breathable fleece helps regulate temperature and wick away moisture, keeping you comfortable and dry. The Arc'teryx Kyanite Hoody Women's excels in breathability with its very breathable material that offers a lot of breathability and does an excellent job of regulating temperature. It allows air to get in and out really well, making it ideal for high-output activities. The Mountain Hardwear Summit Grid™ Hoody, while comfortable, doesn't offer the same level of breathability. Therefore, if breathability is a priority, the Kyanite Hoody is the better choice.

Weather Resistance

2.1/ 5.0

Weather resistance is an important consideration for fleece jackets, as it determines how well the jacket can protect you from wind and light precipitation. The Mountain Hardwear Summit Grid™ Hoody provides decent protection against wind and light precipitation, making it suitable for mild outdoor conditions. It is a reliable choice for going outside, camping, and hiking. The Arc'teryx Kyanite Hoody Women's, however, is not windproof or water-resistant and lacks a DWR coating, making it less suitable for windy or wet conditions. Therefore, if weather resistance is a key factor, the Summit Grid™ Hoody is the better option.
