What is it?

Thermal R is Marmot's proprietary family of polyester insulations specifically engineered to meet various cold weather needs.

How does it work?

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.

What are the benefits of this technology?

Thermal R insulation is resilient, has excellent warmth to weight, and is highly durable.
