Have you ever stepped away from a campfire on a cold fall night and immediately thought about that warm feeling you get after climbing into your sleeping bag and zipping yourself up? Well, what if I told you your sleeping bag didn’t have any zippers?

Sierra Designs Backcountry Bed 700 Review Breakdown


Unlike every other sleeping bag I have ever used, the Backcountry Bed does not have any zippers. I was skeptical about this at first because there is nothing more comforting to me than climbing in my bag and zipping up on a cold night. However, after seeing how easy it is to slide your feet in and use the integrated hand pockets in the comforter to tuck yourself in, I am entirely sold on the concept. You don’t have to worry about snagging your zipper as you zip up your bag, and the oversized comforter provides plenty of warmth. On warmer nights, you can simply fold the comforter over the bag, allowing you to vent the entire top half of your body.

The top/shoulder area of the bag is wider than the foot of the bag, which makes the bag feel roomy. There is plenty of room to transition yourself to your side or stomach if you need to adjust yourself in the middle of the night.

At the foot of the bag, there is a zipperless foot vent that allows you to slip your feet out of the bag if you get too warm and need to get your feet out. Simply raise your knees and slip your feet out of the vent.

This allows you to tuck your sleeping pad into the bag, keeping it aligned with the bag as you toss and turn in your sleep. I toss and turn quite a bit and have woken up in the middle of the night because part of my body was off of my pad and on the cold tent floor. Having this sleeve kept me on the pad the entire night.

The oversized comforter on this bag made it feel different than other bags I have used. As the name suggests, tucking myself into the bag made me feel like I was tucking myself into my bed. The comforter is soft and warm, and truly feels cozy. After a long day of hiking, you will be relieved to tuck yourself in for a good night’s sleep.

While we were out testing the bag, the temperatures at night dipped down into the mid-30s, and the Backcounty Bed 700 kept me warm the entire night. This is not surprising seeing as the bag has an EN comfort rating of 28 (F) and an EN limit of 16 degrees (F).

Since the no-zipper concept was new to me, I was worried that the comforter might become untucked, or that I would have to keep adjusting it throughout the night. I turn over several times as I am trying to fall asleep (not restlessly, but occasionally) and the cinch cord system kept the comforter over the top half of my body.


At 2lbs 8oz, the bag is light for a 20-degree bag. You might find lighter quilt options, but they might lack the comfort and warmth of having an oversized comforter.

The bag packs down to an acceptable size. Here is a comparison with a 30-degree down bag (on the left).

At $289.95, the Backcountry Bed 700 is not cheap, but it isn’t that much more expensive when compared to other quality bags in the 20-degree range. The EN limit is slightly lower, so consider it a warm 20-degree bag. It is tough to do a true price comparison due to the unique style of this bag. As I mentioned in the design section, I was originally skeptical of the zipperless design, but now having used the bag, I am entirely sold on the concept, and even prefer it over zipping myself up. Because of this, and the high quality materials used, I find the price totally worth it.
