THERMOLITE® insulation provides lightweight warmth for all activites. We use THERMOLITE® insulation in many of our sleep system products in different forms.
Sleeping bag liners use THERMOLITE® fibre knitted to create our Reactor THERMOLITE® fabric.
Sleeping bags use THERMOLITE® insulation that is designed for superior warmth and exceptional softness.
Our insulated Air Sprung Cell™ sleeping mats use THERMOLITE® insulation that is designed with high loft for excellent lightweight warmth with superior durability. The THERMOLITE® insulation lofts up inside the Air Sprung Cells™ to prevent convective heat loss from your warm body to the cold ground.
