We made a favorite even warmer. Take our most popular 20 degree model, the Swallow, add a full collar and additional fill, and you have a rock-solid three-season bag that packs remarkably small while maintaining room to sleep comfortably. The Lark represents an excellent option for those who sleep on the cold side or push their adventures well into the colder evenings of spring and fall.
UL: Ultralight. Pertex® Endurance® 10 denier water-resistant/breathable fabric.

United StatesExcellent Bag
High quality sleeping bag with excellent warmth to weight ratio. Buought the bag to use in the lower 20s and have been kept warm the few nights that I have used it already. This bag is definitely comfort rated to 10° and I added 2 ounces of overfill for extra warmth. Feathered friends was very easy to work with and I am extremely happy with this bag! Quite expensive but worth the investment 100%! Would recommend to anyone!

Excellent bag for sure, way more comfortable than my 37 year old down bag. We had an unseasonably cold snap on our AT journey and it kept me toasty at 24 degrees with a 35 mph wind under a tarp. Really like the baffles around neck. Love it. Thanks

Keeps me warm
I've been using it on the PCT in sub freezing temps and I'm staying warm. I will say that a little more info/advice from store staff would have been helpful. No one explained the baffles. I learned about them elsewhere.
