Lark Nano 10 Sleeping Bag

Take our most popular 20 degree model, add a full collar and additional fill and you have a solid 3-season bag that still packs smaller and lighter than most bags with a warmer rating. The Lark represents an excellent option for those that tend to sleep on the cold side.

* Required Fields


  • Mummy shape (average width) with #5 YKK two-way, separating zipper with locking sliders
  • Full collar provides an effective seal of down around your neck to trap the heat
  • Trapezoidal footbox allows your feet to fall in a natural pose without compressing the sides
  • 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
  • Generous draft tube prevents cold air from seeping past the zipper
  • Overlapping dual-webbing zip guard guides the fabric away from the zipper and eliminates the need for a stiff or heavy fabric layer that can interfere with the draft tube seal
  • Includes storage bag & stuff sack

Light and WarmReview by Joe
I finally got a chance to use this bag in the conditions it was designed for. As a Boy Scout leader, I slept in 21 deg F condtions. I sleep cold and have had trouble staying warm in similar conditons using other bags. But, not this time. I was comfortable for the first time in cold weather! Great quality and service in a light weight bag. (Posted on 11/4/2013)
