Big Agnes Diamond Park Sleeping Bag: 15F Down

The Diamond Park Sleeping Bag is the premiere option in the Deluxe Camping collection from Big Agnes for many reasons. Its zip-off quilt creates a 3-in-1 layering system. You can take the quilt out and use the sleeping bag like a regular mummy, or you can rely on the quilt solely for summertime backpacking trips. Together, the bag and quilt provide a 15F temperature rating with its light, lofty down insulation. Big Agnes treated the down to retain its lofty warmth when wet. The ripstop shell also has a water-resistant treatment for greater defense in wet climates.
