The thermal performance of this fleece sleeping bag liner makes a great addition to your sleep system by adding up to 18 degrees (C) of extra warmth.

It also works really well as a stand-alone sleeping bag in warmer weather and if you have warm base layers, you may even find it comfortable at lower temperatures. Be aware that moving air will pass through the fleece material easily; so you need to be inside a shelter or use a tarp or poncho to keep you away from drafts.

The great part about using a Thermolite® Reactor Fleece Liner in summer is that if you are sleeping out in sandy or dusty conditions (for instance on a paddle trip, or mountain biking in the desert), you can take the Reactor Fleece Liner home and just throw it in the washing machine: it is much easier to take care of than a down sleeping bag. 

WARMTH:

Made of a polyester fleece material with hollow-core Thermolite® fibers which trap extra air. This provides significant warmth without the weight or bulk normally associated with fleece materials. A technical hood with a drawcord closure and a shaped foot box enhance the thermal performance of this liner, while a one-third length zipper allows for easy entry and some ventilation. Rather than a specific temperature rating, we simply provide a guideline: the Thermolite® Reactor Fleece will add a season to your existing sleeping bag (make sure that the other components of your sleep system, particularly the sleeping mat, are up to the task).

LIGHTWEIGHT:

The Reactor Fleece Liner tips the scales at a mere 13.4 ozs / 379 g. Because of its warmth to weight ratio, the Reactor Fleece Liner is an obvious choice to boost the performance of your sleeping bag in winter. You may also want to include it in your emergency gear for cold weather trips.

COMPACT:

The Reactor Fleece Liner comes in its own Ultra-Sil™ stuff sack. Its uncompressed pack size is only 8” (20cm) long x 5” (13cm) diameter.
