Feathered Friends Tanager 20 Sleeping Bag review

The Feather Friends Tanager 20 CFL Sleeping Bag is a hoodless, full length, and zipperless sleeping bag designed for thru-hikers, ultralight backpackers, and alpinists who want to minimize their gear weight and bulk. Weighing 18.6 oz, the Tanager is insulated with 12.6 oz of 950 fill power goose down and is best viewed as a specialized, ultralight alternative to a 20 degree backpacking quilt or mummy sleeping bag. It’s not designed to span a wide temperature range like a backpacking quilt or a hoodless sleeping bag with a zipper, although it is lighter weight than comparable quilts and hoodless sleeping bags at the same temperature rating.

The Tanager 20’s sweet spot is for trips where you know that nighttime temperatures will range between 20 degrees and 50 degrees at night. It’s also an excellent option as an inner bag, if you want to stack a quilt on top, because it’s draft-proof. There’s no sleeping pad attachment system to fuss with and no hood, so you can roll around in it at night or side sleep, just as you would with any hoodless sleeping bag.

The Tanager 20 is cut wide so you can sleep with gear or water that you want to keep warm at night
The Tanager 20 is cut wide so you can sleep with gear, clothing, footwear or water that you want to keep warm or dry at night.

Like a quilt, the Tanager is designed to be used with an insulated hood, long underwear, and socks. The top closes with a drawstring over the top of your shoulders. There isn’t a draft collar or draft tube at the top of the bag to seal around your neck (wish there was), so you’ll want to wear an insulated hood with an extended neck like the Montbell Down Balaclava or an insulated hooded jacket in the Tanager to keep your head warm and create a good seal at the top of the bag.

I’ve taken the Tanager down to 20 degrees and the lack of a side zipper is no great loss. Getting in and out of the bag is as easy as putting on or taking off a pair of pants. In warmer temperatures, you can regulate the Tanager’s temperature by opening the drawcord and venting the bag around your neck. If you have an insulated jacket, you can also push the bag partially down your torso, so it traps less heat.

There’s a drawstring, offset to the right, to cinch the top shut, but no draft collar or draft tube around the neck.

Feathered Friends bases their sleeping bag temperature ratings on the use of a hood, long underwear, socks, and a sleeping pad with a minimum R-value=3.  The Tanager 20 has continuous baffles, so you can push its 20 degree temperature rating a few degrees lower by shaking the down from the bottom to the top and sides, which is one of the benefits of this type of baffle construction.

The Tanager 20 is a full length sleeping bag, not a so-called elephant’s foot or partial length bag. It’s available in two lengths: 68″ and 74″, which should reach the height of your neck so that it can be cinched closed over your shoulders. The Tanager is also cut fairly wide, with a shoulder / waist / foot girth of 62″ / 52″ / 38″, which puts it on par with wide sleeping bags. This lets you can store extra gear in it at night that you want to dry or keep from freezing, like gloves, shoes and water bottles.  With these dimensions, getting in and out is not a problem and you don’t feel claustrophobic in the Tanager. The wide shoulder girth also makes it relatively easy to vent the Tanager as temperatures rise. Finally, the footbox is trapezoidal and roomy, so you can sleep with your feet straight up or on their sides.

Recommendation

The Feathered Friends Tanager 20 is a hoodless and zipper-less full length sleeping bag that weighs 18.6 oz. While it is lighter weight than many comparable quilts and hoodless sleeping bags, it isn’t as versatile, since it is harder to regulate your temperature in warmer weather. Still hoodless sleeping bags, including the Tanager 20, are simpler to use than quilts in colder weather because they don’t rely on a pad attachment system and they’re far more draft resistant. If you use a mummy bag today for spring and autumn camping, but are hesitant to switch to a quilt, the Tanager 20 sleeping bag might be a great alternative.

Personally, I’ve decided to switch from a 29 0z, mummy bag to the Tanager, chopping 10 oz off my spring gear list, with no loss of comfort since I carry a hooded insulated jacket already. That said, the Feathered Friends Tanager 20 is a specialized bag and it’s not going to suit everyone’s tastes. But colder weather quilts are not the slam dunk that warm weather quilts are, and the Tanager 20 and hoodless sleeping bags can be an attractive option if you want to combine the weight benefits of a quilt with the draft resistance of a sleeping bag.

  1. Interesting alternative to a quilt and guaranteed draft free. Love the weight. Thanks for reviewing this! Sound like it will be perfect for this spring.

  2. Is this tent able to withstand the pressure of additional rain?

    • I’m sorry, I meant to say sleeping bag. Is this sleeping bag able to withstand rain soaking it (i.e. will it remain dry and warm)? Curious because I often camp outside in the elements.

      Thanks.

      • No. it’s just a sleeping bag. The fine weave of the exterior fabric is really intended to keep internal tent condensation from making it to the down interior, but that’s about it.

      • I’m curious then if there are other sleeping bags on the market that can withstand a soaking rain. Typically, I just cover my bag with plastic sheeting on the outside and crawl inside the bag, and that keeps the bag mostly dry (although there is the issue of keeping my head dry, so often my head is soaked and chilled on the ground). But it would be much easier to just have a bag that would stay dry on it’s own in the elements. Any suggestions?

      • No. You need to buy a bivy sack or a tarp.

      • The thing is bivy sacks and tarps are so bulky and hard to carry on backpacking trips. I’m looking for a lighter, but rainproof sleeping bag that will not get cold or wet with downpours. Or at least a better workaround than plastic sheeting because it is very uncomfortable to have a cold and wet head when sleeping. Are there any more effective makeshift solutions you can think of?

    • One thought I had was to line the sleeping back I have with leaves (or whatever brush I can find where I am sleeping) to provide extra insulation and waterproofing. Would that make sense?

      There is still the issue of a cold, wet head. Would it be feasible to stick a pillow of some sort on to the edge of the sleeping bag and then add a zipper with holes to breathe through? The primary concern is keeping dry in a downpour.

      Thanks in advance for your help.

  3. Sleeping bag is cool and all but how about that tent?

    • It’s a Tarptent Stratospire 1 and it is extremely weather worthy, for both wind and rain. It’s actually about twice as waterproof as the mainstream tents that you can buy at REI with a hydrostatic head of 3000mm. Dual vestibules too, for a one-person tent, so you can hunker down in it if you need to wait out a storm. This one is made with silnylon but the 2 person version is also available in DCF.

      • Now that you mention it – yeah…Stratospire. I didn’t look closely at the top. From that angle I was thinking Aeon, and that’s a long term review I’m looking forward too.

  4. It seems like they’ve gor the fabrics on this bag backwards. Wouldn’t it be better to put the 15d on the outside and use the 7d as the liner?

    • The larger 15d yarns create bigger air gaps where they intersect which allows for better vapor transfer, while the 7d yarns provide greater water resistance because the holes are narrower.

  5. Very nice bag, and the color rocks. I wish it had a small zip on the footbox for ventilation. That would expand the temperature zone quite a bit for maybe a 1/2 ounce penalty. BTW, when I use my EE Convert, I never use the zip. It’s faster and easier to get in-n-out with the zip always closed. I even asked EE to make me another Convert, just like this one, without a zip. But they shot me down. Are the width dimensions for the long really the same as the short version ?

    • You could probably pay someone to put one in. FF might do it or Rainy Pass.

      I’d call FF about the long’s dimensions just to check.

      I think we’ll see the hoodless bag category grow in terms of options over the next few years. They really are an attractive option over sleeping pad attachment systems. Note how they’re all offered by EE, KB, and Zpacks. I think there’s a reason for that.
