Rab Nimbus Jacket (Summer 17)

The Rab Nimbus Jacket is a lightweight synthetic jacket designed as a lightweight insulating layer for damp conditions. The Pertex Quantum outer is lightweight, breathable and windproof whilst the Cirrus insulation is a synthetic insulator which attempts to emulate down, but without the drawbacks when it gets wet. It's contained in stitch through mini baffles which provide good insulation coverage throughout the jacket. The hood is able to be used under or over a helmet and has a lycra bound opening.

Cirrus insulation combines the benefits of down with synthetic fill. It is in fact a synthetic insulation that unlike others has not been formed into a sheet. Instead it remains a loose water resistant down like fibre that expands to form a "cloud of warmth". It will deliver the same warmth for its weight as 600 fill power duck down. As well as lofting properties Cirrus is very compressible as well as robust. It's also very fast drying allowing Cirrus to get back up to its full insulation potential a lot faster than Hydrophobic down or synthetic insulation that is formed into a sheet.

Reviewer: Rick, Sapporo  

I've worn this jacket as an extra layer over one winter season backcountry skiing and snowshoeing in Hokkaido. I also find myself wearing it around town and cycling to work quite a lot. On first appearance it seems quite thin but it provides good warmth for its weight and blocks wind well. Rab say Cirrus is equivalent to 600FP down and that seems about right. The DWR finish takes care of rain showers with ease. It's light and packs into its own pocket - just, though I tend not to bother.

I'm 5'11" and lanky with long arms, and the Medium is a good fit, plenty of length in arms and torso. It is just roomy enough to throw on over other jackets at rest stops etc. Pockets are a good size. The hood is elasticated but has no adjustment, so while it will go over or under a helmet if you are wearing it bare headed or with a beanie it is a bit roomy and will not turn with your head. This was not a big problem for me.

Overall, this is a very useful bit of kit, and the beauty of it is not having to worry about getting it wet.
