REI

With smart goose down insulation distribution and a waterproof shell, this cold-weather bag is warm, weatherproof, and very compressible.

  • Goose down is efficiently distributed for maximum warmth and comfort—800-fill-power goose down on top and 700-fill-power goose down underneath
  • Ultralight nylon shell features Gelanots® waterproof, breathable coating for superior weather protection
  • Vertical Baffle construction lets the goose down remain fully lofted and keeps it from shifting and migrating, preventing cold spots
  • Vertical Baffles also prevent down from shifting to the sides and keep more down on top of the bag where it keeps you warmer
  • Exclusive dual Regulator zippers adjust temperature as needed—fully close both zippers to increase warmth, open inner zipper to decrease warmth
  • Multi-chambered hood and contoured, insulated draft collar seal in heat; trapezoidal foot box increases comfort and provides more space
  • Relaxed fit from hip to knees increases comfort by providing space to move around in
  • Includes nylon stuff sack and large cotton storage bag

Not too shabby!

Rating:****
I bought this to replace a heavy, bulky synthetic that was rated to -10 degrees F. Size and weight are fantastic. It sure makes those 15+ mile legs a bit easier where taking off a couple of pounds gives you that much more comfort. The extra space allows for a bit more room in the pack.

I'm not too sure about the -20 rating. Used it on a number of occasions where it went sub zero at night. Not close to -20, but below zero. I found I still had to wear a layer of polypro to stay nice and warm on those nights. For a bag rated for -20, you should be able to go commando. Not in this bag.

Like all things down, heavy moisture is the bane of this bag. I suppose that's the advantage of synthetic. The outer layer of the bag did a fairly good job at keeping the majority of the moisture out, but some still gets in at times.

Not a good choice for sub zero if you're a bivvy bag kind of person. In tents though, this thing is fan-freaking-tastic. Never had any issues that weren't easily remedied in a four-season tent.

Be sure to leave the bag hanging for storage instead of using the oversized storage bag they give you. Keeping it in the case will cause the down to clump up, reducing it's effectiveness. There's a loop on the bottom of the bag for this. If it does clump up, a trip through the dryer will fix it.

Three stars because it's still really good. Five stars go to the bags I've pooped bricks over. This wasn't one of them, though it's still really great for what it offers.

Sweet Bag

Rating:*****
I bought this bag for a 3 month expedition in Patagonia. After much research I decided this bag was the one and I do not regret my decision. This bag was roomy, warm, and light. I was comfortably warm at 0 degrees and paired with silk liner warm well below that. I would not recommend this bag for temperatures above freezing because it is so well insulated you get really hot. However, having said that, the two zipper design allows great regulation of warmth. I love this bag. Oh, not recommended for wet weather, but that goes for any down bag.

A great sleeping bag!!

I used this bag on a 3 night Presidential Traverse March 4-7 of 2008 with temps dipping below 0 and was utterly warm. Roomy enough to stash my gloves, shell jacket, soft shell jacket, and myself in a down parka and still zip up nice and cozy. Only complaint, my feet got a little cold .... otherwise its a great bag.

Kilo excels in all conditions

Rating:*****
I've used this bag in a multitude of scenarios and temperatures. It works best when it's colder, but with the multi-zipper system, you have plenty of ventilation flexability. Great packer, and partnered with a good pad, this bag works well in any cold-weather backpacking environment.

Note: be careful around extreme wet conditions.

I love my REI Kilo !

Rating:*****
I have used this bag in almost all conditions, and I can't say enough about it. My friends also rave about it and some have even bought one of their own. I bought mine about 4 years ago, and this has been one of my best purchases ever. I highly reccomend it!

Toasty Warm and Very Light

My wife and I each had one of these on our Kilimanjaro climb. They were warm and comfortable, but my wife's should have been regular length, even though she's not over 5'6".

Great bag

I have been down to -10 deg. with this bag and stayed warm, and I was in a hammock! If I could change anything, I would have a left hand zipper.

I replaced my Western Mountaineering Bag

Rating:***
Great bag!

Its so warm!

I was suffering from cold at nights with my Western Mountaineering bag. It looked great on paper, being light and rated at the very low temperature. But it turned out to be over rated. The shell tour easily and it wasn't very water repellent. Hard to imagine considering the huge price Western Mountaineering charges.

The Kilo is truly made to be a expedition bag. The insulation and protection is great. The price is great.
