Lark 10 YF 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 YF 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.

Our YF line of sleeping bags feature a lightweight, 100% nylon Pertex® Quantum® shell that uses yarns with unique Y-shaped filaments to create a fabric with increased downproofing and water beading properties, even after years of use and washing.

YF: YFuse. Pertex Quantum® 20 denier mini-ripstop fabric
