Ward off winter’s chill with the light weight, highly compressible Opti-Warm Fabric from Merrell. You will find it in many of the jackets, pants and boots that Merrell has created to keep you warm. Opti-Warm Fabric is available for both performance and casual wear. One of our favorite features is the loft retention so you can easily pack it when traveling.
The outside layer keeps out the rain and the cold, while the synthetic insulation layer is designed to reflect body heat and keep you warm.
