Description

Sea to Summit's Reactor Polar Sleeping Bag Liner is the kind of gear that experienced hikers and winter campers always praise: «The warmth boost is incredibly good - and with so little weight.» That's exactly what the inner sleeping bag was developed for.
The Thermolite® EcoMade Fleece fabric with grid structure and hollow fibres guarantees excellent thermal performance at a low weight - perfect as the core of an efficient sleeping system in cold weather. In combination with a sleeping bag and a good mattress, the lining can significantly increase thermal performance.

Thanks to the zips at the shoulders and the adjustable drawstring at the feet, it's easy to control the temperature in the liner. The cut is inspired by a mummy sleeping bag for maximum thermal efficiency and integrates perfectly into the Free-Flow-Zip system of Sea to Summit sleeping bags. In warmer conditions, the liner can even be used as an independent ultralight sleeping bag.

Practical when camping: the footbox can be opened, allowing you to move around a bit without getting out of the sleeping bag. HeiQ Fresh Odour Control also ensures that the material stays fresh even after long journeys - a real advantage on multi-day trips or winter camping trips.
Whether you're camping in the snow, on a cold night in a cabin or on a hike in late autumn: the Polar Liner Reactor has everything it takes to considerably increase your comfort zone during sleep.

Additional information
Details

HeiQ Fresh

HeiQ Fresh is a modern odour control technology from the innovative Swiss company HeiQ Materials AG. It effectively prevents unpleasant odours in textiles by neutralising odour-causing molecules before they take hold. The treatment means that clothes - especially those worn intensively for outdoor, sporting or everyday activities - stay fresher for longer and need to be washed less often. This increases comfort and saves resources at the same time.
Material

Recycled materials

Recycled materials are made from recycled raw materials, such as old PET bottles, fishing nets or textile scraps, and offer an ecological alternative to conventional synthetic fibres. They are lightweight, robust and high-performance, in no way inferior to new materials and, at the same time, help to conserve resources and reduce waste. Ideal for all those who prioritise sustainability and functionality in their outdoor adventures.

Polyester

Polyester is a synthetic fibre characterised by its high resistance, dimensional stability and ease of maintenance. The material absorbs little moisture, dries quickly and is also very durable. Polyester is often used in outdoor and functional clothing as it is lightweight, robust and versatile, and can be used as an outer fabric, lining or in mixed fabrics for greater comfort.
