This is the previous model of the Lark UL. For the new model with more colors and sizes, check out the NEW Lark UL 10 Sleeping Bag

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.
