## Summary description

SEA TO SUMMIT Reactor Lightweight R is a lightweight sleeping bag liner in pewter color designed to boost warmth and hygiene inside your regular-fit sleeping bag. It serves as a thermal layer that increases comfort, reduces need for washing the main bag, and is suitable for backpacking, travel and seasonal camping. Compatible with rectangular/regular sleeping bags.

## Long 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.
