Camping is more fun without the mummification.

Deep shivers and constant cramping should never keep you up at night. The 0-degree, down-insulated, and roomy Kelty Coromell Sleeping Bag ensures that you don’t regret your decision to spend the night in the woods.

  • Slanted baffles hold 550-fill down insulation in place to keep you cozy on cold autumn or spring nights or during mild-weather winter camping
  • Semi-rectangular shape provides plenty of room for bunking down, and the bag unzips flat for use as a quilt
  • An insulated hood cinches down to lock in body heat but also zips off for comfort in warmer weather
  • Two-way locking zipper, zipper draft tube, and drawcords lock in the warmth
  • A zippered chest pocket lets you store your headlamp so you can find it when nature calls
  • Ground-level side seams prevent heat from escaping as it rises
  • External loops anchor the bag to your sleeping pad
  • Lightweight compression stuff sack for saving pack space during backpacking and camping trips
  • Comes with a storage sack and has hang loops for different storage options

Room & Warmth Galore

Ok, so it's a little big, and a little heavy for you minimalist types. But if you're a rolling, cold, side-sleeper like me this is the bag for you. Finally a comfortable night sleep while backpacking! It's almost perfect. I wish it were a little lighter for certain and the zippers and hood are a bit difficult to navigate in the dark. But the room! I don't feel squished or sausaged, and I can roll with abandon. Bring on the Zzzzzz.

Perfect for me!

I love this bag. Its my first winter bag and feels like with the right care, will last a long time. Kelty's design for this bag is great for people who don't mind a little extra bag weight and would rather have the extra wiggle room. The picture above is accurate--it's not a traditional mummy cut, but it's a little tighter than rectangle bags. SOOOO comfortable when I used it in the Wisconsin winter, with temps ranging from -5 to 30 degrees. With a light insulating layer, a good sleeping pad, and a hot water bottle in a wool sock down by your feet--this bag is absolutely perfect for what I wanted. Even without the hot water bottle, the draft collar most certainly did it's job and I never felt the bitter air. Love the full zipper, the zip off hood, and the material of the bag. I also use it as a comforter in my cold-ass college house. It comes with a nice big storage bag AND a great compression sac. As an upgrade (if you're worried about a wet bag) I got a Sea-to-Summit eVent Compression Dry Sac, size medium, for this bag and it fit perfectly. Chest pocket is nice for your headlamp too. Overall--plenty of room for extra pillows, SUPER warm, and great fit for someone who likes to move in their sleep. Can't wait to use it again!

Perfect for me!

PS. I used the bag in a lean-to, so yeah, it gets the job done even with a frozen light layer of snow on the outer shell of the bag.

It's warm, it's roomy, it squishes down small, and it's not very heavy. The manufacturer's size estimates are accurate. I wouldn't take it to the Sierras in January, but it's fine for temps in the teens.

Does anyone know how small this bag...

Does anyone know how small this bag compresses to?

Stuff sizes are: (reg and long garnet) 9 x 14 in, (regular molten lava) 9 x 17 in, (long molten lava) 10 x 19 in. You could probably get it a little smaller with a compression sack

what is a compression sack? does the sleeping bag comes with it?

Great Bag

I bought this bag for my Winter ski tours. Brought it to Norway and it worked great without a tent! It wasn't terribly cold, maybe 15-20deg overnight but I was toasty warm inside. I love the cut. Most mummy bags are a little uncomfortable because I often lay on my side but this bag is perfect. Just enough room to move a bit inside, especially in the toe area, but not too big for a standard size sleeping pad. Not to mention, the price is a big win! Mine was $100.

My Favorite Bag

I acquired on of these early last year and I have to say, it's relegated my Western Mountaineering to 2nd tier. Main reason is comfort! It's plenty warm, but with much more room to move than my other mummy bags. It's not the Most compact bag ever, so I recommend getting a compression stuff sack for it. I now save the WM for only trips where weight and size are a significant issue. Otherwise, the comfort and resulting better sleep I get with this bag, more often than not takes priority.

FYI- I also makes a great comforter at home when the house is a bit cold.
