Roomy down bag with versatile sleeping options; quilt or mummy bag

The Big Agnes Diamond Park 15 is perfect for those who want extra space and versatile sleeping options, with unique quilt-like construction that turns your bag into a backcountry bed plus a zip-off option to create a quilt or mummy bag with the Park Series Wedgie (sold separately). With a roomy, rectangular shape and 600-fill DownTek insulation, the Diamond Park is great for three-season base camping and road trips.
This bag is uninsulated on the bottom to create a lighter, more compressible sleeping bag. It requires a pad underneath for insulation. Pad and pillow sold separately.
