The Sea to Summit Silk Blend Sleeping Bag Liner combines ultralight Thermolite® yarns with natural silk for a soft, luxurious layer that adds modest warmth and helps keep a sleeping bag cleaner. Thermolite Pro fibres use permanent ceramic pigments to absorb and reflect the body’s infrared energy, while Thermolite EcoMade fibres provide lightweight warmth from recycled textile waste. Mummy versions use shoulder openings for easier entry, exit and temperature regulation; the Rectangular version adds a pillow sleeve and Comfort Stretch Panels.

Key Features

  • Ultralight comfort: A smooth, low-bulk blend of Thermolite yarns and silk adds softness and modest warmth inside a sleeping bag.
  • Thermal efficiency: Hollow Thermolite fibres trap insulating air, while Thermolite Pro ceramic pigments reflect infrared energy back towards the wearer.
  • Freedom of movement: Stretch side panels flex as you turn and change sleeping position.
  • Mummy access: Shoulder openings create a wider entry and exit without the weight or bulk of a side zipper.
  • Travel-ready rectangular design: The Rectangular version works as a hygienic travel sleep sheet and includes an integrated pillow sleeve.
  • Stays fresher: HeiQ Fresh FFL helps neutralise body odour without biocides.
  • Easy care: Machine washable; using a liner reduces the need to wash your sleeping bag.
  • Lifetime guarantee: Backed by Sea to Summit’s guarantee against defects in materials or workmanship.

Materials and Technologies

  • Main panel: 72% polyester / 28% silk.
  • Stretch side panel: 85% nylon / 15% elastane.
  • Thermolite Pro: Engineered hollow fibres contain permanent ceramic pigments that absorb the body’s infrared rays and reflect them back to the wearer.
  • Thermolite EcoMade: GRS-certified fibres made from 100% textile waste for durable, lightweight warmth with a lower material footprint.
  • HeiQ Fresh FFL: Biocide-free odour control based on a bio-based amino sugar polymer.
  • Colour: Moonlight Grey.

Care and Use

  • Machine wash with standard laundry detergent.
  • Do not use fabric softener, which can reduce moisture-wicking performance.
  • Air drying is recommended; if machine drying is necessary, use a cool setting.
  • The liner adds some warmth by trapping insulating air. Choose a Sea to Summit Reactor liner when a larger thermal boost is required.
