Recent 3-Season Down Sleeping Bag Reviews

rated 4.5 of 5 stars
Kelty Cosmic DriDown 20

The Kelty Cosmic 20 is one of the most affordable sleeping bags you can find that's filled with down insulation. Although it's not exceptional in any particular aspect, it provides decent comfort and warmth in a package that is small and light enough for some 3-season backpacking. Unfortunately, its 550-fill power down doesn't offer impressive loft or substantial benefits compared to synthetic insulation. Sliding into a fluffy sleeping bag after a long day of hiking is one of the most satisfying… Full review

Marmot Angel Fire

Solid and comfortable sleeping bag. Durable and also very comfortable inside. A great choice for those looking for a soft, comfortable sleeping bag. The extra little pockets inside the sleeping bag also ensure that your belongings do not get frozen or wet. If you are looking for a great and warm sleeping bag for women the Marmot Angel Fire is a very good option. This sleeping bag is ideal for trips where you need or want a little bit of extra comfort and cosiness. At 1.3kg, it is not the lightest… Full review

Sierra Designs Cloud 800/20 Degree

A uniquely designed zipper-less sleeping bag that boosts a much better sleeping experience yet needs to improve on some points. The Sierra Designs Cloud 20 is an innovative 800 FP Dri-Down filled sleeping bag that weighs around 800 g. It shifts from the conventional mummy shape by losing the zipper (that always get snagged) and having a comforter instead. I chose it for its design (had enough of snagged zippers), weight-to-warmth ratio, and its price point, being on the cheaper end of down sleeping… Full review

The North Face Gold Kazoo

Lightweight and compact, but is nowhere as warm as it claims to be. I get cold outside of the summer months. I'm 33 and male and I find this thing cold in anything but summer. I usually have to wear a bunch of other layers and sleep in my down jacket as well if I want to use it in autumn (and I mean mid autumn). I am pretty tall and skinny and not the most cold resistant, but the adverstised temperatures for me are bogus. When I use it out in the wilds somewhere I am always lying awake and cold… Full review

The North Face Gold Kazoo

Comically misrepresented by TNF as to how warm it is. Let me just say, I like TNF products generally. I have had four sleeping bags by them.  This one is a complete, total, abysmal failure. I have the slightly older model (the orange one with yellow inside). It's rated at COMFORT down to 30 degrees, and this is almost criminal to say. This bag only has 11 ounces of 650 down in it. There is no way that is going to keep a person warm down to 30 degreesF. NO WAY. And guess what? This bag doesn't even… Full review

Sea to Summit Trek TK II

Good blend of performance, weight, and price. Spent WAY too much time searching for a sleeping bag that hit my top three "must haves" Lightweight Warm Not constricting Tried Big Agnes, North Face, a very attractive offering from Thermolite, REI's own brand, etc...  Finally decided on the Trek TKII after a test of the TK I version at my local REI.  It met my top three musts closely enough to earn a top rating. The Good: This is a semi-rectangular bag, not a mummy bag. That means is the shape is… Full review

Patagonia Hybrid Sleeping Bag

Did some winter cold camping last year in about 10 degrees above temps. It kept me toasty warm. The extra footbed warmth saved my toes and the two-way zipper was great when I needed to use my hands. It is extremely light and great for backpacking. Very packable and light. Love the hood on the bag, cinches down nice to keep the face warm. The two-way zipper is great for sitting up and being able to use your arms. I did some winter camping with it in about 10 above temps. The extra warmth in the footbed… Full review

Western Mountaineering VersaLite

The Western Mountaineering Versalite is just an overall great sleeping bag. While a bit on the pricey side, the Versalite is a well thought out sleeping bag design that is roomy, provides great warmth for its weight, and utilizes quality materials and construction. The Western Mountaineering Versalite is a great choice for anyone who has reached the point where they are looking to invest in a sleeping bag that will provide great performance in a very lightweight design. Overview I’ve owned a number… Full review

Katabatic Gear Palisade 30° Quilt

A great quilt with top notch materials. It is a bit higher price point than its competitors. The issue many people have is correct sizing. The quilt seems to run a little small unless you are a dead still back sleeper. Size up!! Really nice quilt. Warm, light, durable, and well designed. The price point was a bit higher than competitors at the time of my purchase and I think that has been the primary drawback of this product for me. I have seen other online reviews, in particular Outdoor Gear Lab,… Full review
