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. Filled with premium 900+ fill power goose down, 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 treated with a DWR (durable water repellent) finish.

Details

  • 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

Warm and fluffy

Light, fluffy and compacts very well. I have not used it in Below Zero temperatures(Celsius) yet but it appears to be very warm. Zipper works well. Love the extra feature of opening by the toes.

Great Bag

I bought this bag for my wife and she loves it. Only got one night camping it so far, the temp got into the low 30s and she's a very cold sleeper so she needed a bit of extra insulation in order to keep warm, nothing against the bag, she would probably be cold even in a 0 degree bag

Super Warm and Cozy

I got the Lark YF10 in December and finally got to test it out in January. I went out for a quick overnight with temps that started around 20F and dipped to 0F by morning. I was nice and warm all night and the bag was super cozy. I move around a fair amount when I sleep and space was never an issue. At 6'2" the long option was perfect for me with room for water and extra clothes at my feet. This bag met and exceeded all of my expectations and I'll be buying a lighter model to replace my warm weather bag ASAP.
