100 g Cirrus synthetic insulation
Here's what other sites are saying:
The fear-no-cold Stoic Women's Welder Insulated Softshell Jacket outfits you for long days in deep cold with 100-grams of light weight Cirrus insulation and weather-shunning, four-way stretch softshell material. Stoic's extremely-compressible synthetic Cirrus insulation holds body heat close without adding un-needed weight, while fully-welded construction offers a highly-dynamic fit for un-inhibited motion. The Welder Insulated's 3-D ergonomic fit puts an end to mobility-restriction without weighing you down in excess fabric, and the fully adjustable hood fits over either a helmet or a beanie depending on what you have your sights set on for the day.
