Product Information


The Trek Tk II 18 Down Sleeping Bag from Sea to Summit is a spacious bag for spring, summer, and autumn trekking. With a tapered rectangular shape, you can move around as you sleep instead of laying awake, feeling claustrophobic. The 2D PermaShell™ fabric is treated with DWR (Durable Water Repellant), making this a great bag for just about any adventure!


  • Tapered rectangular shape is spacious, but warmer than a typical rectangular bag
  • 2D PermaShell™ is a high-density nylon-woven fabric with a DWR (Durable Water Repellant) finish to deal with moisture
  • Differential-cut shell with 3D side walls
  • 60/40 fill ratio
  • Side block baffle
  • Zip draft tube with anti-snag
  • Cushioned internal hood drawcord with dual adjustment
  • Two-way YKK® #5 zips with separate foot zip
  • Large-sized internal zip pocket is a great place for your headlamp
  • Includes lightweight Ultra-Sil® compression bag
  • Includes a mesh (cube-shaped) storage pouch with an extension collar which can be pulled out and used when drying the sleeping bag in a dryer.
