Our range of men's synthetic insulated jackets offers an alternative to down insulation. Synthetic insulation is an exciting area for fabric technology right now and is seeing constant progress and innovation as manufacturers try to emulate the warmth to weight ratio that we get from down products by using featherless technology. At Rab® that development has lead to the creation of our Cirrus™ insulation.

Cirrus™ technology is made up of water-resistant synthetic fibres designed to mimic the structure of natural down; this helps to create what could be described as a synthetic down jacket rather than a coat filled with blocks of insulation. This advancement in synthetic technology means that our men's insulated jackets offer a better warmth to weight ratio than ever before, without the use of feathers, while also being able to handle moisture and wet weather better than a down jacket can.
