Rab's Nimbus Jacket synthetic jacket features a unique insulation that claims to come "as close as possible" to the insulating properties and warmth-to-weight ratio of down, while maintaining the favorable moisture management properties of a synthetic.
The Cirrus powered by 3M Featherless insulation is blown into the garment, like down. The whole thing is sheathed in a Pertex Quantum 20D shell for superior warmth, wind and water resistance.
