The Rab® range of women's synthetic insulated jackets offer an alternative to down insulation. Synthetic insulation has taken huge strides in recent years as manufacturers aim to emulate the warmth to weight ratio that you get from down products but using featherless technology. At Rab® that development lead to the creation of our Cirrus™ insulation.

Cirrus™ technology is made up of water-resistant synthetic fibres designed to mimic the structure of down plumage; this helps to create almost a synthetic down jacket rather than a coat filled with blocks of insulation. This advance in fabric technology means that our women's insulated jackets[link] are able to handle moisture and wet weather better than a down jacket can while maintaining a better warmth to weight ratio than ever before without the use of feathers.

If you're still interested in a down jacket, check out our range of women's down jackets.
