Sleeping Bag Inlets & Liners

Extend the life of your sleeping bag and improve sleep hygiene with our collection of sleeping bag inlets and liners. Lightweight and compact, a liner keeps your sleeping bag clean, adds extra warmth in cold weather, or doubles as a lightweight travel sheet in warm climates or mountain huts.

Read Buying Guide: Why Use a Liner & How to Pick the Material ▼

1. Why Do You Need a Sleeping Bag Liner?

  • Protects Your Investment: Body oils, sweat, and dirt degrade down and synthetic insulation over time. Washing a liner is simple; washing a technical sleeping bag reduces its warmth and lifespan.
  • Boosts Temperature Rating: Thermal liners can increase your sleeping bag's warmth by +3°C to +15°C, turning a 3-season bag into a winter-ready setup without buying a second bag.
  • Hut & Travel Sheet: In mountain refuges, hostels, or warm summer nights, use the liner on its own as a clean, breathable sleeping sheet.

2. Choosing the Right Material

  • Silk: The ultimate lightweight choice. Ultra-compact, soft against the skin, naturally temperature-regulating, and adds around +2°C to +5°C of warmth.
  • Cotton: Durable, comfortable, and affordable. Great for camping trips where ultra-light packing is not a primary concern.
  • Microfiber / Polyester: Fast-drying, moisture-wicking, and budget-friendly. Excellent for high-humidity environments.
  • Thermolite® / Fleece: Maximum thermal insulation. Adds significant warmth (+8°C to +15°C) for extreme winter camping and high-altitude mountaineering.

3. Shapes: Mummy vs. Rectangular

Match the liner shape to your sleeping bag: choose a mummy shape for technical alpine bags to minimize weight, or a rectangular shape for traditional camping bags or hostel stays.
