We designed the Tanager to meet customer requests for a pared down, ultralight 20 degree sleeping bag. When we started sourcing materials for this bag we thought no way will a 7 denier fabric hold up to the abuses of a long haul hike...but our testers on the PCT and CDT proved us wrong. The incredibly light fabric, premium 950 fill down, and streamlined design that foregoes a zipper and hood makes this the bag you want in your pack if weight is the ultimate consideration. For maximum efficiency and warmth in cooler temps, pair the bag with a lightweight, hooded down jacket, like the Eos. 

Ideal for: Thru Hiking, Ultralight Backpacking, Alpinism, Emergency Bivy 

CFL: Crazy Freaking Light. Pertex® Quantum® 7 denier water-resistant/breathable fabric. 


  • Drawcord closing around the collar to cinch down opening and keep heat in.
  • No zipper to conserve weight and bulk
  • Made with new Pertex® Quantum® 7dx5d fabric with DWR
  • May be worn with a lightweight hooded down jacket for additional warmth. Designed to be worn with our Eos jacket.
  • Intended for ultralight hikers and alpine climbers for whom every ounce counts.
  • Color: Citron
  • Stuff sack and cotton storage bag included

My go-to 3 season bag.

I’ve had my Tanager for two seasons and a couple of dozen nights, including nighttime temps into the mid- to upper 20s. Used as it’s supposed to be used—with a light hooded down jacket, warm thermal pants and some down socks—the bag is a champ. On one night of 32 degrees I took the down jacket off and just put on a cap as I was too warm otherwise. In a pinch I can even use it during temps in the 50s by simply leaving more of my upper body out of the bag. The quality is terrific, the zipless design was easy to get used to, and the weight was exactly as advertised. If you’re looking for a super lightweight 3-season bag, this is it.

What I’ve come to expect

I’ve had very limited time in this bag but I had high expectations and hopes. For expectations: I already have two Flickers (20 and 40 UL wides) and have been super impressed with the craftsmanship, comfort, durability, and warmth of them (and incredible flexibility with the Flickers), so I expected the Tanager be similar. It is. For hopes: I’d hoped that I could love the form factor of this bag in addition to, but not in spite of its weight. So far so good. I’m enjoying it’s straightforward approach.

Perfect Bag

This sleeping bag is a home run and much more versatile than the similarly purposed Vireo. It's my go-to alpine climbing bag year-round except for Rainier in the winter. The sleeping bag is warm and the fabric is surprisingly durable and resistant to condensation. I find the temperature rating to be consistent with other Feathered Friends down sleeping bags. If you haven't used a hoodless design before, know that you'll need learn simple techniques to keep your head warm such as wearing your hoods to bed and using a balaclava in colder weather. Learning this simple skill is worth the weight savings when every ounce counts. Now if only Feathered Friends would make 0 deg and -20 deg bags with the same fabric for higher elevation alpine pursuits!

Verdict is still out"

Took this bad boy out on an early 3day spring alpine backpacking trip. Temps got down to 30-36. I definitely stayed warm ish, with my 6.7R rated mat, and thermal layers on. I was hoping to be toasty and it didn't happen. I am a 5'2 female and was easily able to fit entirely in the bag and cinch it over my head. On the plus side, insanely light and packs down sooo small. I am still sort of skeptical about the benefits of the no zipper approach. Harder to use as a blanket around camp when you hang outside with friends. I will give it another go in the summer and stick with my winter bag another month.


Great bag- not super warm though

I'm hiking the PCT, and have used this for a month on this trail and a week on the JMT in the Sierras. It's great in many ways ways- super light, soft, fits my body well. But, on coldish nights in the 30's or even 40's I get cold. On the night my water bottle froze, I was extremely cold, I barely slept. I think if you're a woman, add 3 ounces down to the bag. I spoke to another hiker with this bag on the PCT and he loved it, but he's a burly guy. So, if you are a warm blooded man, you may not need to add down. If a woman, or a man who sleeps not warm, add down. I just wish I had known before I ordered that I could have done that.
