The Cirrus Flex features Primaloft's Silver Luxe synthetic insulation. After fairly extensive research it's hard to sayexactly what this means, so here's an attempt to describe it in layman's terms:The 'Luxe' element refers to the fact that this particular type of Primaloft is a little different to your average, being more down-like in both its look and its feel. In practise, this is pretty hard to notice, but having had a look through the figures the basic gist is that it's a bit heavier and a bit warmer. One of the added benefits ofLuxe, aside from its performance, is that it's made from 100% recycled materials.

Rab's move towards more sustainable fabrics and fills is notable across the board, but no more so than within the Cirrus, where virtually everything is recycled. If this weren't enough, it also features a fluorocarbon free DWR, which adds to its environmental credentials. The Cirrus uses Rab’s ‘Slim Fit’ which means it sits close to your body for optimal performance, but you can still fit a couple of thin layers on underneath it. Primaloft Silver sits just below Primaloft Gold, which is their most premiuminsulation. Gold tends to be used in flagship technical pieces that require the utmost warmth, but it comes at a cost. Silver seeks to compromise in this respect, as it still provides good warmth to weight - it's just that it doesn't provide quite as much as Gold. In the case of the Cirrus, Gold would realistically be too warm, so the inclusion of Silver is spot on as far as performance is concerned.
