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.

Other Features:

• Low-profile cordlock lets you un-cinch the hood with one hand

• Insulated tube along upper hood opening seals out drafts when cinched
• Pillow Barn – keeps your pillow tucked in tight all night
• No-draft collar, no-draft wedge, no-draft zipper
• 600 fill DownTekâ„¢ repels water while maintaining insulating value – bluesign® Certified PFOA and PFOS free water repellent chemistry

— Fits pads 25-30 in. wide and 78 in. long; rectangular pad recommended
— Sleeping pad sold separately
• Lightweight ripstop shell for high performance and a soft feel
• Compartmentalized, horizontal baffled construction prevents down shifting
• Double zippers allow entry from either side of bag and when unzipped allows top of bag to be used like a comforter
• Top and bottom zippers allow for maximum venting
