Product information

Description

The SEA TO SUMMIT Reactor Lightweight R sleeping bag liner in pewter is a thin, rectangular liner designed to increase the thermal efficiency and hygiene of regular-fit sleeping bags. Made as a lightweight inner layer, it adds measurable warmth to existing sleeping systems without significantly increasing bulk or weight, and it is suitable for backpacking, travel and seasonal camping where added comfort and reduced laundering of the main sleeping bag are desired.

Advantages

This lightweight liner provides an extra thermal layer that raises the effective warmth of a sleeping bag while remaining compact and easy to pack. It protects the interior fabric of the sleeping bag from sweat and dirt, making maintenance simpler and extending the main bag's service life. The rectangular cut and regular fit are compatible with many standard sleeping bag shapes and allow for freedom of movement. The pewter color offers a neutral, low-visibility finish that suits multi-season use.

Suitable for

  • Backpacking and multi-day hikes where low weight and compactness are important
  • Travel and hostel use for hygiene and comfort
  • Seasonal camping to add a thermal boost to an existing sleeping bag
  • Situations where easier cleaning and reduced washing of the primary sleeping bag is preferred

When it may not be suitable

This liner is not intended to replace a purpose-built cold-weather sleeping bag; users needing substantial additional insulation for extreme conditions should select a properly rated sleeping bag. Because it is a lightweight and thin thermal layer, it will not provide the same warmth as a full insulated bag on its own.

Key specifications

  • Shape: rectangular, regular fit
  • Weight category: lightweight liner
  • Intended function: thermal boost and hygiene layer inside a sleeping bag
  • Color: pewter (neutral/low-visibility finish)
  • Compatibility: designed for regular-fit sleeping bags and rectangular sleeping bags

How to use

Place the Reactor Lightweight R inside your regular-fit sleeping bag so that it lies flat against the inner fabric; align the head and foot ends to match the bag's shape. Use it as a liner between you and the sleeping bag to gain the added thermal effect and protect the main bag from perspiration and dirt. After use, air the liner and launder according to the manufacturer's care instructions to maintain fabric performance and hygiene.

What to consider before purchase

  • Confirm your sleeping bag is regular-fit and rectangular to ensure compatibility
  • Decide whether you need only a light thermal boost or a full insulated bag for your intended temperatures
  • Check care instructions and fabric type if you require machine-washable or quick-drying materials

Usage recommendations

For best results, use the liner in conjunction with a sleeping bag that fits your body and intended temperature range; combine with a quality mattress or sleeping pad for improved insulation from ground cold. Regularly airing and occasional washing of the liner will keep your main sleeping bag cleaner and extend its usable life.
