Yep, a down sleeping bag is widely known for its lightness, compared to the synthetic one. Even so, there are still lots of products that weigh more than three pounds, which are certainly still burdensome to travel. Before we go any further, let’s agree on one thing: an ultralight sleeping bag doesn’t mean those that are extremely thin and can’t provide warmth. In fact, without compromising on warmth, these bags come as light as feather and can be compressed small. After all, aren’t you tired of carrying that bulky and heavy sleeping gear? Here’s a guide to the top ten lightweight sleeping bag that you should consider.

Frequently Asked Questions (FAQs)

Let's dive into these questions!

Which one is better: down or synthetic sleeping bags?

It depends, of course! If you are looking for a sleeping bag that is compressible and can last up to decades, then the down type is best. However, to get this dream feature, you have to spend more. And that’s where synthetic wins. Even so, the synthetic sleeping bag is less compressible and break down sooner after continuous stuffing and re-stuffing.

What to consider when buying a sleeping bag?

Never go without a plan. First, determine your budget to narrow down the abundant options. After that, decide whether you want a sleeping bag with synthetic or down feathers for the insulation type. Temperature rating is the next point to check so that your main needs of warmth are fulfilled. You can select the shape and weight afterward to ensure it fits you well without weighing you down.

What's the best way to store my sleeping bag?

The first thing you have to do is release air from the bag, starting from the foot out of the top. You can roll up the sleeping bag and tuck it into a slightly larger stuff sack to make it easier. Using a waterproof stuff sack is a smart choice when rain is a real possibility. Keep in mind that keeping your bag compressed for an extended period of time will reduce the bag’s loft. If you’re not planning on using it, it’s better to keep it outside of its compression stuff sack.

How to wash my sleeping bag?

If only a few parts are stained, you can spot clean it by making a paste of a little non-detergent soap and then brush gently. If a complete wash is required, you should check and follow the manufacturer’s washing instructions.

Promising review:

I took this out on an early fall trip to the southern part of the Adirondacks, and it was great. A bit warm on nights that were above 60, but that's expected with a bag rated for 20F. The stash pocket and lining are my favorite parts.

Nemo Disco - Best Lightweight Down Sleeping Bags: Ideal for side sleepers!


Ideal for side sleepers!

price from
Our opinion:

Featuring a generous size, the perk of having a Spoon™ shaped bag is the availability of a wider space than the mummy shape. It means that you can sleep in whatever style you want. This spacious value is certainly a gift for side sleepers who often have trouble in tight bags. When the temperature drops, Nemo Disco hugs you like a cocoon, but you can also unzip the ThermoGills to let out warm air.

Promising review:

Great bag, I have the large size, very comfortable with lots of room to toss and turn. I’m 6’ 3” 245 pounds and this is the only bag I have owned that doesn’t make me feel claustrophobic! Great weight and size for serious back packing.

It remains dry

price from
Our opinion:

This down sleeping bag is designed for climbers, skiers, and backpackers with a temperature rating of 15 degrees Fahrenheit. What’s cool about this bag that is rarely found in other products is its glow-in-the-dark zipper pull that helps you get out of the nest when you wake up at night and want to do your duty. To ensure that your bag remains dry, Mountain Hardwear has coated the Phantom with a durable water repellent (DWR) finish.

Promising review:

... This thing is light, packs down small, and is super warm. I've been taking it backpacking here in CO this spring in weather between 25 degrees and 40 degrees. I think I have 7 nights in it so far. With a liner I think I could easily take it down to 0. It is also super comfortable and the fabric feels like silk. Foot box is huge and my feet are always toasty. The DWR is a nice touch. ...
