Category: Three Season Bags

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.

Sophia ★★★★★

Even with the old color options, this bag packs down impressively small for a 20-degree quilt and the draft collar is a game-changer for cold sleepers like me. I stayed perfectly warm on a damp 30-degree night in the mountains.

Kevin ★★★★☆

The draft sealing at the neck is better than I expected for a previous model bag. It's plenty warm for cool summer nights in the mountains, though I wish the zipper didn't catch quite as often.

Claire ★★★★☆

The shoulder baffle holds warmth really well, and I stayed cozy down to about 25 degrees last weekend. It packs down smaller than I expected for a 20-degree bag, which is a nice bonus. Just wish the previous model had a draft collar like the new one.
