Silk Blend Sleeping Bag Liner
Silk Blend Sleeping Bag Liner
3 Shapes · HeiQ Fresh · Travel & Hygiene · Ultralight

The Silk Blend liner adds a layer of warmth and comfort to your sleeping bag without weighing down your pack. Available in Compact Mummy, Mummy, and Rectangular with Pillow Sleeve shapes, it works equally well as a backcountry sleep upgrade or a hygienic travel sheet.

Three Shape Options
Choose Compact Mummy for shorter users and tighter packs, Mummy for full-length coverage with shoulder snaps for temperature regulation, or Rectangular with Pillow Sleeve for travel and hostel use.
Comfort Stretch Panels
The Rectangular version includes stretch panels along the seams that move with you when you turn over in your sleep.
Easy Entry and Exit
Shoulder snaps open the liner wider than typical zippered designs, without adding weight or bulk.
Stays Fresh Longer
HeiQ Fresh odor control neutralizes odors on multi-day trips, releasing them at the next wash to refresh the treatment.
Climate Core of Your Sleep System
Acts as the climate-regulating middle layer in any sleep setup — adding warmth in winter, wicking moisture in summer, and protecting your bag year-round.
