Arcteryx says about the Therme SV Parka Men's
Distinctive in its design – and made for the harshest winter days – the Therme SV Parka delivers extended protection from snow, sleet, rain, wind, and biting cold. Comfortable and quiet, the breathable 2L GORE-TEX is waterproof and windproof. A high amount of responsibly-sourced 750 fill goose down is light and exceptionally warm. The design allows the down to form to the body for maximum effectiveness, Coreloft™ synthetic fill is used to warm areas prone to moisture, and the insulated hood tops off the coverage.
