Light, highly packable, and named after the Japanese phonetic for 'exploration', The North Face Tansa Hybrid ThermoBall Jacket is made for fast–and–light mountain adventures. Enjoy dual protection as you climb higher: ThermoBall insulation at the core and neck locks in warmth, while WindWall fabric completely blocks out chilly wind. With zipped pockets and a stuff sack included, this jacket is not only protective, but practical too.
