New for Fall 2025: Our Lark 10 UL gets all-new Pertex® Quantum Pro® shell fabric + Pertex® Diamond Fuse lining fabric in the footbox, plus new and familiar colors
We made a favorite even warmer. The Lark is a rock-solid three-season sleeping bag built for comfort and performance when the nights turn cold. With a full down collar, additional fill, and premium 950+ fill power down, it delivers exceptional warmth while still packing down surprisingly small. A great choice for those who sleep on the cold side or venture deep into the shoulder seasons of spring and fall.UL: Ultralight. Pertex® Quantum Pro® water-resistant/breathable fabric with 950+ Fill Power Down
