Performance Evaluation

Fabric Performance

  • Breathability: The REI Co-op Magma Trail Quilt 30 excels in breathability thanks to its high-quality Pertex® Quantum nylon shell. This fabric is designed to be lightweight and allows for excellent airflow, preventing overheating and moisture buildup inside the quilt. During warm nights, the breathability of the material ensures a comfortable sleeping experience without feeling clammy.
  • Waterproofing: While the quilt itself is not entirely waterproof, the down insulation is treated with a durable water repellent (DWR) finish. This treatment allows the down to resist moisture, maintaining its loft and insulating properties even in damp conditions. The outer shell also features a DWR finish, providing an additional layer of protection against light rain and morning dew.
  • Durability: The 15-denier Pertex® Quantum nylon used in both the shell and lining offers a great balance between weight and durability. Throughout testing, the quilt withstood rough handling, frequent packing, and exposure to various elements without showing signs of wear or damage. The robust construction ensures that the quilt can endure the rigors of long-term backpacking and camping trips.

Weather Resistance

  • Cold Weather: The Magma Trail Quilt 30 is rated for temperatures down to 30°F, making it suitable for three-season use. During testing in chilly mountain conditions, the quilt provided ample warmth, particularly when paired with a high-quality sleeping pad. The down insulation performed admirably, retaining heat and ensuring a cozy night’s sleep.
  • Warm Weather: In warmer conditions, the quilt’s design allows for versatile use. The partial zipper enables you to open it up completely, transforming it into a blanket. This flexibility makes it comfortable for use in a range of temperatures, from cool to warm nights, without causing overheating.
  • Wind Resistance: The tightly woven Pertex® Quantum fabric offers good wind resistance, which is crucial for maintaining warmth in breezy conditions. The quilt’s design, including the draft collar and draft tube, further helps to seal out cold air and retain heat.

Practical Features

  • Draft Collar and Tube: One of the standout practical features is the draft collar and tube along the zipper. These components effectively minimize heat loss and prevent cold air from seeping in, enhancing overall warmth.
  • Footbox: The integrated footbox is a thoughtful addition, keeping your feet comfortably warm and preventing drafts. This design element is particularly beneficial in colder weather, where retaining heat is essential.
  • Pad Straps and Sleeves: The adjustable pad straps and sleeves are highly functional, ensuring that the quilt stays securely attached to your sleeping pad. This feature prevents the quilt from shifting during the night, maintaining consistent insulation and comfort.
  • Packability: The Magma Trail Quilt 30 shines in its packability. It compresses down to a remarkably small size, easily fitting into a backpack without taking up much space. This compact nature makes it an excellent choice for backpackers who need to maximize their packing efficiency.

Overall, the REI Co-op Magma Trail Quilt 30 delivers impressive performance across a range of conditions, making it a reliable and versatile choice for three-season backpacking and camping.

  • Material Comfort: The interior lining of the Magma Trail Quilt 30 is made from soft, 15-denier nylon, which feels gentle against the skin. This material choice enhances overall comfort, making it pleasant to use even directly on bare skin. The quilt’s high-quality down fill also contributes to its plush, cozy feel.

This makes it an excellent choice for backpackers who need to minimize their pack weight. Its compact size when packed is another major advantage, allowing for easy storage and transport.

  • Versatility: The quilt’s design allows it to be used in various ways. It can be fully enclosed for maximum warmth or opened up and used as a blanket in warmer weather. The adjustable pad straps and sleeves add to its versatility, ensuring it stays in place regardless of your sleeping setup.
  • Comfort: The soft 15-denier nylon lining and the well-designed footbox enhance overall comfort. The draft collar and tube effectively minimize heat loss, providing a cozy sleeping environment in cold conditions.

Overall, the REI Co-op Magma Trail Quilt 30 offers numerous advantages, especially for those prioritizing weight, packability, and warmth. However, it has a few limitations that potential users should consider based on their specific needs and preferences.

Comparative Analysis

When comparing the REI Co-op Magma Trail Quilt 30 to other top contenders in the market, such as the Feathered Friends Swallow UL 20 and the Kelty Cosmic Down 20, several key differences and similarities emerge.

Feathered Friends Swallow UL 20

The Feathered Friends Swallow UL 20 is renowned for its exceptional warmth and lightweight design, similar to the Magma Trail Quilt 30. Both products use high-fill-power down insulation (850 for the Magma and 950 for the Swallow), ensuring superior warmth and compressibility. However, the Swallow UL 20 is rated for lower temperatures, making it a better choice for colder weather conditions. The Swallow UL 20 also features a full-length zipper, providing greater versatility for temperature regulation but adding a bit more weight compared to the partial zipper design of the Magma Trail Quilt 30. The Swallow UL 20’s price is significantly higher, reflecting its premium materials and construction, which may be a consideration for budget-conscious hikers.

Kelty Cosmic Down 20

The Kelty Cosmic Down 20, on the other hand, is a more budget-friendly option compared to the Magma Trail Quilt 30. While it offers good warmth with its 600-fill-power down, it falls short in weight and compressibility compared to the Magma’s 850-fill-power down. The Cosmic Down 20 is also heavier and bulkier, making it less ideal for minimalist backpackers who prioritize pack weight and space. However, for those looking for an affordable sleeping bag that performs well in moderately cold conditions, the Kelty Cosmic Down 20 is a solid choice. It features a full-length zipper and a more traditional mummy bag design, which may appeal to users who prefer a fully enclosed sleeping experience.

In summary, the REI Co-op Magma Trail Quilt 30 stands out for its lightweight, packable design and high warmth-to-weight ratio, making it an excellent choice for three-season backpacking. While it may not provide the extreme cold-weather performance of the Feathered Friends Swallow UL 20 or the affordability of the Kelty Cosmic Down 20, it strikes a compelling balance for those who need a versatile, high-quality quilt for various conditions.


The REI Co-op Magma Trail Quilt 30 is an outstanding choice for backpackers and campers seeking a lightweight, versatile, and high-performing sleeping solution. Its 850-fill-power down insulation provides exceptional warmth without adding bulk, and the quilt’s compact design makes it easy to pack and carry. The durable Pertex® Quantum nylon shell and the practical features such as the draft collar, footbox, and adjustable pad straps enhance its usability and comfort in diverse conditions.

While it may not be the most budget-friendly option, its superior materials and thoughtful design justify the investment for serious outdoor enthusiasts. The Magma Trail Quilt 30 is particularly well-suited for three-season use, offering flexibility in both warm and cool weather. Overall, it delivers excellent value for money, making it a reliable and highly recommended choice for backpackers looking to minimize weight without compromising on warmth and comfort.
