- Use the stitched-in FlipItâ„¢ Footbox for toasty toes in quilt mode; to convert to an enclosed sleeping bag, flip the footbox inside out, tuck in the quilt corners and zip
- 850-fill-power Downtek™ PFC-free down maintains insulating value even while wet, using bluesign®-approved PFAS-free compliant water-repellent chemistry
- Big Agnes Signature Diamond Quilting prevents down migration while using less stitching than traditional quilt lines, saving weight and providing better loft
- Ultralight ripstop nylon made from recycled fishing nets keeps weight low using durable and sustainable fabric
- Low-profile cordlock cinches the top of the bag to keep heat in
- Full-length, 2-way zipper provides easy temperature regulation in sleeping bag mode and can be separated for quilt use
- Insulated anti-draft collar locks in warmth to increase thermal efficiency
- 4 sewn-in loops so you can attach to a pad with straps of your choice
- Anti-snag #3 zippers for a smooth, quick zip
- Includes a mesh sack ideal for long-term storage and a smaller stuff sack for active use
- To pack down this bag to its minimum compressed size, Big Agnes recommends pairing it with a Big Agnes Compression Stuff Sack or Superlight Girdle (not included)

Nicely made! Great feet pocket.

This item is ideal. I am a long term traveler to less developed countries and need a quilt at times, sitting around a campfire or covering up in an overnight bus. As for the sleeping bag function I need more than a liner but less than a bulky camping sleeping bag to survive sketchy hostels and unexpected colder nights where the provided blanket is not enough. I tried the bag at home before my departure and it performs well, except for the zipper which sometimes gets caught in the material. I was considering giving four stars because of the high price, but my REI membership entitled me to a break. Also the company does not discriminate against tall people as they charge the same for the long version.

Comfy!

I'm a hot sleeper, but always feel like I need covers, so I was looking for something that take camping here in NC where it's always humid and the temperature frequently ranges anywhere from hot to super hot, even at night. While I haven't taken this out camping yet (first trip is in a couple weeks), I gave it a test run on my couch and had a great sleep! It's surprisingly comfortable and luxurious feeling, something I'd actually choose to snuggle up in rather than just tolerate. I also love how the bottom of this is made--use it as a bag, or stick your feet out if you like!

Great Quilt – A Must-Have for Variable Conditions
4 weeks ago
I took this quilt on a 7-day backpacking trip along the Pacific Crest Trail in June 2025, and it exceeded my expectations. During the day, the temperatures were scorching, but the nights—especially around campsite—got surprisingly chilly, dropping into the upper 30s and low 40s. At first, I wasn’t sure I’d need it, especially paired with my warm sleepwear setup. But it turned out to be a game-changer. I combined it with a warm fleece layer, and it kept me perfectly comfortable through the night without overheating. The quilt’s versatility and packability really stood out. Lightweight, easy to deploy, and warm when it counts. Highly recommended for shoulder season hikes or any trek with large temperature swings.

i believe the temp rating on this is 50 degrees and i slept in the whites in a hammock with this at 40 degree temps, and only had a couple warm layers on and kept me warm just fine, also had no underquilt, so to me it’s a 10/10 product, packs up very small and is so light
