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.

Still the late autumn challenges ahead but so far I feel that in 2 lbs/1 kilo category this is the best 3-season bag I've ever had.

took my new bag on a test drive for a couple of nights at 11,500 feet. The nights were cold and the bag was warm.

United StatesFirst impressions
Used it one night at 11,600 ft with outside temperatures dipping to 40F. As expected, the bag kept me toasty warm. What impressed me that even at temperatures well above its rating the bag remained comfortable. Will have to wait until later in the season to judge its performance at lower temperatures

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!
