* Required Fields


  • Mummy shape (wider width) with #5 YKK two-way, separating zipper with locking sliders
  • 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
  • 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

Amazing sleeping bag!Review by Nicholas
An incredible quality sleeping bag, well worth the investment! I don't need to discuss the specs, you can read them here and they are accurate. Incredibly high quality down, super light weight materials but durable at the same time. I would highly recommend! I also decided to go with the Swift bag because of the extra space, I was willing to add a few extra ounces. I tend to move around in my sleep and this bag is just enough space while remaining very comfortable. 5 stars! (Posted on 5/2/2016)
