The Rab Women's Cirrus Flex Jacket might look, feel, and pack like a down insulator, but since it's synthetic it stays warm in wetter, damper environments. The insulation sits on the lighter side for full-year versatility. It has the packable warmth you'd like whether you're summer alpine climbing or hut-to-hut touring in wintertime. A windproof, water-resistant shell ensures protection in most weather conditions. The Cirrus Flex also features a storage pocket for compact packability letting you take it with you wherever you roam.
