The Big Agnes Greystone 20° mummy-style sleeping bag is a lightweight wonder that combines value, performance, and sustainability. It's perfect for backpacking, yet flexible enough for couch surfing. Featuring 600 fill DownTek insulation, recycled shell and lining fabrics, and a PFC-free moisture - repelling coating, this bag ensures you stay warm and comfortable outdoors. With a regular bag weight of 1.02g / 2.25lbs, a fill weight of 539g / 19oz, and a traditional mummy shape, it's your go - to for outdoor adventures.


Using your Greystone 20 down sleeping bag is easy. Just unroll it in your tent or on your couch and crawl in to enjoy the warmth. When packing, roll it up tightly and secure it with the straps. For cleaning, it's best to take it to a professional cleaner as it has special insulation and materials. Store it in a cool, dry place, preferably in a loose storage sack to keep the down fluffy. Avoid getting it too wet as much as possible, but if it does, let it dry thoroughly before storing. This will ensure your sleeping bag lasts for many outdoor trips.
