It uses 800 fill power goose down, along with a synthetic blend to bring you the best of both worlds when it comes to warmth per weight and weatherproofing ability. So we award major points in the insulation and size category as this is still lightweight enough to be a great option for backpackers.
This bag is approved for complete comfort sleep in 15 and 30 degrees, and because you can get very snug inside of the mummy design, we award tons of points for comfort.
We like that this comes complete with moisture resistant and treated ripstop nylon that will help to keep water out of your bag so that the down maintains its loft and warmth.
We also like the extra-large zippers that work to prevent snags and rips in your bag which can result in shedding and loss of down. We award points for durability here.

This bag is lightweight and works well for backpackers, though it has a small mummy design so it’s definitely not going to work as a double sleeping bag. Points for size here. It is also treated to resist water, though it is advised to keep this bad boy as dry as possible.

And while this bag is still lightweight (weighing in at around 3 pounds), it is a touch heavier than the previous options on our list which weigh in at 2.5 pounds and less. So we take a few points away in the size category as every ounce counts for a backpacker.
While other options on the market feature a hood that has velcro and drawstrings (many of which show up as complaints on user reviews as these can snag and rip the bag), the hood on this is quite simple.
You might not get quite the custom fit that you’ll find with other bags, but you’ll get close to the same warmth, so we award points for comfort and durability here.

Criteria Used for Evaluation
When considering a bags insulation, we look at how closely reviewers find it to hold up to its advertised temperature rating. We made sure to only include options in our list that far succeeded consumer expectations in this regard.
Here, we look at how well a product breathes and feels throughout the night. No one wants to invest in a bag that's not going to perform one of it's most important duties - being comfortable.
For durability, we consider the ripstop fabric, if the zipper is snag-free if lots of shedding occurs, and how well it holds up to water.
We value a lightweight bag for the trail which weighs in typically under two pounds. We do feature some heavier products on this list too, though. It's worth considering the heavier one for specific uses, mostly where you won't be weighed down while hiking out to your camping spot.
In terms of value, we like to bring you products that can be used through multiple seasons so that you can get more use out of them.
Expert Interviews & Opinions
Shopping for a sleeping bag can be tough, and with so many options on the market--all with their own various claims--it can be hard to know where to pull the trigger.
So we’ve researched some of the key differences between synthetic and down sleeping bags to try to help clear things up for you so that you can make an informed purchase that will leave you a happy camper.
There are pros and cons of both synthetic and down bags, and we’ve broken them down for you here.
Down Sleeping Bags:
Down sleeping bags are incredibly soft and light. Because of their make-up, you are able to compress them down to a fraction of their sleeping size and they also weigh next to nothing as well. As we mention in our FAQ section below, the higher the fill power of the down, the warmer it will be while weighing the least.
This makes a down sleeping bag a backpacker’s companion as it works to drive down the overall weight of your pack.
However, you’ll find that your down bag may not be the best tag along if you’re backpacking through nasty weather. Down clumps together when it is wet and takes a super long time to dry. This clumping renders all warming potential null and void, so you’re left with nothing but a sopping wet and freezing lumpy blanket (essentially). Ew.
There are some down bags that are treated with special solutions to make the down water-phobic, but this only works with light moisture in the best of cases--not heavy rains.
So if you’re planning on using your own bag in less-than-pleasant weather situations, you might want to think again.
Synthetic Sleeping Bags:
So pretty much the opposite is true for synthetic sleeping bags.
Synthetics weigh more, are less compact, and do not compress in the same way that down does. This means that you could end up with quite a bulky bag that will add a lot of extra weight to your pack.
However, what synthetics lack in a slim profile, they deliver in warmth while wet. Synthetic fibers are much better equipped to ward off rain and the elements and to stay dry and warm for much longer. Because they don’t clump and don’t maintain the natural tendencies of down, they are able to maintain their shape and keep you warm through the night.
Synthetics tend to ring up on the lower end of the price range as well.
So what should you make of all of this information?
First, consider the weather you are likely to encounter. If you plan to be in dryer regions, then go with a down bag for sure. But if wet and rainy days are in your future, you are likely going to want to go synthetic.
What’s great is that there are a few blended options on the market that will place water-resistant synthetics on the outside while putting soft and cozy down close to your skin. With these, you get to enjoy the best of both worlds.
When checking out the price tag of the down bag you’re about to buy, you might get a lump in your stomach and begin questioning your purchase. Of course, not all down bags are insanely expensive, but most of them are more costly than their synthetic counterparts.
But consider this: if you properly care for and maintain your down bag, it will far outlast a synthetic bag and could likely last you your entire life. When put that way, the price tag no longer seems so startling.
So how exactly do you go about properly caring for your new down bag? We’ve compiled a list of a few helpful steps for you to follow so that you can enjoy your new bag for years and years to come.
1. Avoid overwashing. If you are properly taking care of your bag, you will not need to wash it every single time. We’ll explain more about the proper care to avoid over-frequent washes as this can cause your bag to lose all of its luxurious loft.
2. Don’t get into your bag all dirty. If your clothes are covered in dirt when you get into your bag, your bag is going to absorb the dirt. The same goes for your hair and face. Clean up as much as you can before getting in for the night.
3. Consider bringing a light cotton sheet with you to place between you and the bag. This will help to keep dirt from your bag and it will also keep you a bit warmer as well. You can also purchase a ready-made sleeping bag liner.
4. Let the sun hit your bag and air it out while you’re preparing your breakfast or coffee in the morning before you stuff it back in your sack.
5. Keep your bag out of its stuff sack for as long as you can. Each time you set up camp, make this one of the first things you pull out. Keeping it stuffed for extended periods of time will limit future loft potential and warmth.
6. Opt for spot cleanings when necessary with a toothbrush and soap rather than a full-on washing.
7. Do not store in your stuff pack. Take it out when you get home and let the sun hit it again for between 1 and 2 hours. Make sure it is 100% dry and then hang it up if possible, or store in a large cotton or breathable mesh bag. This will help to prevent mold and mildew from developing on your bag and it will help to keep it smelling fresh as well.

Other Factors to Consider
Because having a snazzy bag to pull out at the sight is just plain fun and can add more of a taste of home.
We value products that have been treated with hydrophobic solutions so they can stand up against water and dry faster when they do get wet.
Frequently Asked Questions
q: What is fill power?
Great question! Don’t let all the numbers fool you--it’s not actually that complicated.
When calculating the fill power of a specific down, one is really measuring the loft. The loft is basically how much space one single ounce of down can fill. Why is this measurement important?
For one reason, the amount of space or loft of down determines two things: how much heat it can trap and how much it weighs.
Ideally, you are looking for down with a super high loft because a single ounce of it can fill more space and trap more heat. That means you get a warmer product that ends up weighing less.
So, for example, if you are looking at a down with 600 fill power, then one ounce of the down fills 600 cubic inches of the product you’re buying.
While goose down and duck down are similar, goose down is considered to be more premium and costs more because it has the capacity to have a higher loft (upwards of 900 fill power). Duck down typically maxes out around 800 if you’re lucky.
q: What is the difference between duck and goose down?
There’s not a huge difference between the two. The reason duck down has now grown in popularity is because the prices on goose down are inching up.
While both go through the same quality control regiments, the reason goose down remains a touch more expensive is because it has the potential to have a higher loft than that of duck down.
q: Is down actually feathers?
So technically the answer to this question is no. Feathers are classified as the longer, more substantive top layer on a waterfowl. The down that is used to make your sleeping bag is what’s found underneath.
Down is smaller, wispy even, and is insanely soft and fluffy. This is key when it comes to comfort because you don’t want to be poked with the sharp ends of feathers.
There are some products out on the market today that use a blend of both, but you’ll find that with premium and well-made products that you are getting strictly down.
q: Can I wash my bag in the washing machine?
Yes! But you should follow our instructions very carefully.
First, make sure that you are using a front loader washer. If you use a top loader, you run the risk of ripping your bag because the washing motion is jerky and harsh.
Then, make sure you have a gentle detergent. You can purchase a detergent that is meant specifically for a down product, or you can go with something gentle like Woolite.
Wash on your washer’s gentle cycle in warm water. Make sure it gets good and rinsed and that it gets put through the spin cycle.
Be very attentive when drying! Place the bag in your dryer on the lowest setting. Throw a couple of dry cotton towels and some clean tennis balls (if you have them) in the dryer along with your bag.
The towels will quickly absorb excess moisture and the tennis balls will work to encourage the down filaments to fill up the entire bag again.
Pay attention! Even if your dryer is on the lowest setting, it may get too heated. Open the door and let excess heat out during the drying cycle. And never let the bag rest on the hot dryer when the cycle is over. It could melt, so you should pull it out immediately.
q: How do I hand wash my bag?
To hand-wash your bag you’ll follow many of the same steps as above, except for you’re the washing machine.
Make sure you have a gentle detergent or one that is specifically for cleaning down.
Fill up your home tub with warm water (same as above) and soak the bag until it is fully saturated. Use your mitts to work in the suds and let the bag soak for a few hours (working in those suds every so often).
Drain the tub and fill with new water to rinse. You will likely have to do this 2 times to ensure that you have rinsed out all of the detergents.
Drain again and this time, roll your bag into a tube. Do not twist the bag or wring it out. This could cause damage to the down and the bag. As you roll, use your body weight to press out excess water.
Lay flat in direct sunlight, flipping regularly. This could take multiple days.
If you don’t have time for that, you can put it through the spin cycle if you have a front loader washing machine and then tumble dry as we outlined above in the previous question.
