Proving why classics have such staying power, the Swallow’s ideal combination of lightweight warmth and comfortable fit has made it a customer favorite year after year. Based on one of our original designs, the Swallow YF is updated with a Pertex® YFuse shell and premium 900+ fill power down. Of our mummy sleeping bags, the Swallow is more spacious than the Hummingbird and narrower than the Swift. An ideal all-around backcountry bag, the Swallow is perfect for a wide range of summer conditions. 

Available in 20 Degree and 30 Degree options.

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 water-resistant/breathable fabric.


  • Passive collar provides an extra cushion 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
  • #5 YKK two-way zipper with locking sliders
  • Top-stitch construction ideally suited to our ultralight fabrics
  • Includes storage bag & stuff sack

Like Sleeping in a Cloud

Love this bag. Saying it’s soft and plush is an understatement. Light and warm too. Used it for Rim to Rim the last weekend in May with temperatures in the mid to upper 30s on the rim. Never had the first chill. I have the 20° model and actually had to dump a little warm air a couple of times. It’s my first FF bag, construction and overall quality look great.

Light, Puffy and Awesome

Haven’t trail tested yet, but hung out in it in my living room. Feels about accurate temp rating-wise and sits right in the middle of my 0 degree bag and my 15 degree bag. It’s heavier than my 30 degree bag yet somehow feels incredibly light. Very comfy materials. I’m sold on Feathered Friends for life.

Great for hiking Kilimanjaro

I used this bag to climb Marangu Route of Kilimanjaro in September and it kept me warm all the nights while others around me were freezing. I love how light it is to pack too!
