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.

Details

  • Continuous baffles let you position the insulation where you need it
  • 3D contoured hood opens wide for warm nights and cinches tight when the temps start to drop

Really Really Nice Sleeping Bag

I received the bag two weeks ago, stuffed it in a dry compression sack and went on a 5 day winter kayak tour on Lake Powell. In the compression sack, the bag slips easily into a 13 liter Big River dry sack. Upon setting up camp, the bag fluffed quickly into its fully lofted form, begging for a nap. Nights were low 20 degrees Fahrenheit and I never fully zipped the bag and was warm and toasty. Finally, it rained and snowed every day and night and at the end of the trip, the Lark was still fully lofted, dry and warm. I definitely recommend this bag!

THERE IS NON BETTER

This is the best bag I've had in all my 50 years of backpacking. It's light, warm at low temps and even into the moderate highs of summer. The Pertex Endurance shell fabric sheds water like a duck, and the dark colors help this bag to absorb heat and conceal the inevitable stains and dirt. The Lark UL has become my goto bag for every outdoor adventure.

Lark LT - very warm and comfy

I just got the bag. They did a great job working with me on finding the best bag and materials. And the bag was so comfortable while camping out on a chilly night in the Idaho desert. This bag replaces my other Feathered Friends Swallow bag that I've had for 22 years. I'm looking forward to 22 more years with the LarkLT and I don't think I'll be disappointed.

Wow, is this bag warm!

I just bought this bag in early October. I'm amazed at the quality of the construction, the luxurious, light fabrics, and the amount of loft from the 20 ounces of down! The bag (size Regular) is roomy and long for my 5' 10", 150 lbs. It has a huge down collar and zipper draft tube. It weighs one ounce less than it's supposed to and lofts up almost stiffly, the down has so much loft!. I have no doubt that with some sleeping clothing layers, this bag would be good to 0° F and below.
