From jackets and pants to gloves and sleeping bags, Marmot's Thermal R™ insulation is our ultra-warm synthetic solution for cold weather activities.
Thermal R™ is Marmot's proprietary family of polyester insulations specifically engineered to meet various cold weather needs.
The unique combination of multi-channel and hollow fibers is designed to provide maximum warmth while reducing the adverse effects of perspiration, condensation and humidity. The fine multi-channeled fiber transports away moisture while the hollow fibers provide excellent loft with minimum weight.
Thermal R™ insulation is resilient, has excellent warmth to weight, and is highly durable.
