  • Functioning like down feathers, the tiny round clusters of ThermoBall spun polyester trap warm air, while softly conforming to your body's shape
  • ThermoBall retains 80% of its insulating power even when dampened by rain, humidity or sweat, so you'll continue to stay warm
  • Small baffles in shell fabric allow insulation to fully expand to retain body heat; highly compressible ThermoBall insulation offers warmth equal to 600-fill-power goose down
  • Tightly woven nylon shell features diamond stitching that helps hold insulation in place to keep it evenly distributed; durable water repellent finish repels light moisture
  • Stretch panels at sides, hem and sleeves increase mobility for climbing, skiing or hiking
  • Zippered hand pockets; full-length front zipper with internal windflap; stretch-bound cuffs; low-profile drawcord hem
  • The North Face ThermoBall Hybrid Jacket for women has a standard fit and is machine washable
  • ThermoBall jackets were thoroughly tested by The North Face athletes, including Conrad Anker and Jimmy Chin, during summit trips on Denali and Mount Meru
