First Impressions of Big Agnes Greystone 20, 600 DownTek Sleeping Bag
The Big Agnes Greystone 20, 600 DownTek Sleeping Bag promises a blend of value, performance, and sustainability, a trifecta that immediately piqued my interest. Big Agnes is a well-regarded name in outdoor gear, and the Greystone’s recycled materials and PFC-free water repellent coating suggest a commitment to responsible manufacturing. As someone who spends considerable time in the backcountry, I’m always on the lookout for gear that minimizes its environmental impact without compromising performance.
For years, I’ve struggled to find a bag that balances warmth, weight, and packability without breaking the bank. My current bag, while warm enough, feels bulky and takes up too much space in my pack. I was specifically seeking a down sleeping bag with a temperature rating around 20 degrees, prioritizing lightweight construction and compressibility for backpacking trips.
Upon unboxing the Big Agnes Greystone 20, I was immediately impressed by its soft, recycled shell fabric and the noticeable loft of the 600 fill DownTek insulation. The bag felt surprisingly lightweight and easily compressible, suggesting it would pack down nicely in my backpack. The build quality appeared solid, with clean stitching and a smooth-running zipper.
Compared to my older, synthetic-filled bag and a pricier 800-fill down bag from another brand, the Greystone seemed to strike a good balance. The 800-fill down bag was noticeably lighter and more compressible, but at a significantly higher cost. My older synthetic bag felt heavier and bulkier. The Greystone seemed to offer a sweet spot in terms of performance and price.
My first impression of the Big Agnes Greystone 20 was excitement. The bag felt like a solid upgrade, promising to deliver warmth, compressibility, and a reduced environmental footprint. I was eager to put it to the test in the field.
Real-World Testing: Putting Big Agnes Greystone 20, 600 DownTek Sleeping Bag to the Test
First Use Experience
My initial testing ground for the Big Agnes Greystone 20 was a three-day backpacking trip in the Sierra Nevada mountains. The nights dipped down to the low 30s, providing a decent test of the bag’s temperature rating. I slept in a lightweight, single-person tent at around 8,000 feet of elevation.
The bag performed admirably in the cool, dry conditions. It warmed up quickly and kept me comfortable throughout the night. The contoured hood snugged nicely around my head, and the no-draft collar effectively sealed in warmth.
I didn’t experience any significant issues during my first use. The zipper operated smoothly without snagging, and the bag felt roomy enough without being excessively large. I appreciated the low-profile cordlock on the hood, which allowed me to adjust the fit with one hand.
Extended Use & Reliability
After several weeks of use, including multiple backpacking trips and a few car camping excursions, the Big Agnes Greystone 20 continues to impress. The bag has held up well to regular use, showing no signs of wear and tear. The recycled shell fabric seems durable and resistant to abrasion.
Maintaining the bag has been relatively easy. I’ve spot-cleaned it as needed with a damp cloth, and I’ve taken care to store it properly when not in use, ensuring it’s fully dry and loosely packed. So far, the DownTek insulation has maintained its loft and warmth, even after being compressed multiple times.
The Greystone has outperformed my previous synthetic bag in terms of warmth-to-weight ratio and compressibility. While it doesn’t quite match the performance of higher-end, 800-fill down bags, it comes remarkably close at a significantly lower price point. I’ve found it to be a reliable and comfortable companion on my outdoor adventures.

- Shell & Lining Fabric: Recycled polyester taffeta with a PFC-free water repellent finish. The use of recycled materials is a major plus, reducing the bag’s environmental impact.
- Zipper: 65″/165cm YKK no5 anti-snag locking zipper. The anti-snag design ensures smooth and reliable operation.
- Weight: Varies slightly by size, but typically around 2 lbs 8 oz (regular size). This makes it a relatively lightweight option for backpacking.
- Stuff Sack Size: 8″ x 15.5″. This compact size allows for efficient packing.
- Other Features: Contoured hood, oversized no-draft collar, no-draft zipper tube, interior loops for a liner, exterior loops for hang drying or storage.

Performance & Functionality
The Big Agnes Greystone 20 performs its primary job—keeping you warm and comfortable—exceptionally well for its price point. The DownTek insulation provides excellent warmth for its weight, and the mummy shape helps to trap body heat. The bag’s features, such as the contoured hood and no-draft collar, further enhance its thermal efficiency.
The bag’s main strength lies in its balance of warmth, weight, and affordability. However, it’s not without its limitations. In extremely cold conditions (below 20°F), you might need to supplement the bag with a liner or extra layers of clothing.
The Greystone meets and slightly exceeds my expectations for a mid-range down sleeping bag. It provides a comfortable and reliable sleeping experience without the high price tag of premium options.

Maintaining the bag is relatively straightforward. Spot cleaning with a damp cloth is usually sufficient for minor stains. For more thorough cleaning, it’s recommended to use a down-specific detergent and a front-loading washing machine.
Accessories and Customization Options

While there are no specific customization options for the Greystone, it’s compatible with most standard sleeping bag liners. You can also use a compression sack to further reduce its packed size. The interior loops make it easy to add a liner for increased warmth or easier cleaning.
