Rab Nimbus Jacket review

Updated: Dec 9, 2020

I've always used fleece jackets for the bulk of my photography with a Gore-Tex over jacket and its been a pretty good combination but I have always understood the benefits of a down jacket, or more to the point a synthetic down jacket.

The main reason I have never owned a down jacket is because of the torturous process of removing down from birds, it is simply terrible and I couldn't possibly support such a nasty process and I urge you to do the same and boycott them.

That was until synthetic down came along, this made me sit up and take notice.

Synthetic down has a few benefits over regular down, when it gets wet it wont clump together like real down does, meaning washing the jacket was much easier and getting caught in rain would be fine too.

Down jackets while very warm do suffer from clumping when wet, even when the down is treated with waterproofing to the down itself. If you wash down jackets the individual baffles seem to lose their shape as the down all clumps together at the lower end of the baffle and despite shaking it when drying they tend not to go back in the right places.

Down jackets are also a lot more expensive than synthetic down so the benefits in my opinion are actually far better on synthetic down over regular down plus you can keep a clear conscious that no birds were tortured for your jacket.

Synthetic down jackets are exceptionally light weight so you barely feel like you're wearing them, they are also able to be folded down to a really compact size so they are perfect as a jacket to be stored in your ruck sack.

The main benefit is they are warm, really warm because they trap layers of air in the synthetic down and hold it very well, they also offer a very good degree of wind proofing.

The down side, They are rarely waterproof and you will need an outer shell to make them a viable all season option so keep that in mind if you intend to purchase one.


The Rab Nimbus jacket has an RRP price of £150 but can be found by shopping around for as little as £100 which puts it at the lower end of price on down jackets, but synthetic down is cheaper.

The Rab Nimbus jacket is designed to be a multi season jacket but as stated would need a waterproof outer and it can be used as a mid layer jacket in the depths of winter rather than a stand alone jacket.

The outer shell of the jacket is Rabs Pertex Quantum windproof fabric and the insulation is Cirrus which is synthetic but lofts just like down.

The Rab Nimbus comes in four colour ways and I went for the dark blue which I believe is called Beluga which has a grey interior, but there are some brighter colours available if thats your thing all with different colour internal liner.

The Nimbus is a hooded jacket which is elasticated but lacks draw strings on the front of the hood to tighten it around the face.

Nicely styled so can be worn anywhere

There are two waist pockets which are a decent size and the left pocket can be used as a stuff sack to fold the jacket up inside itself and be zipped up but if I'm honest I have never been able to get the jacket fully inside it.

There is an internal chest pocket with zip as well which is ideal for a phone or wallet etc.

The sleeves have elasticated cuffs which I felt could have been a little tighter as I do have a gap on them which doesn't cause too much issues but will allow wind to penetrate them.

YKK zips are present all round on the Rab Nexus jacket which are very smooth and work well and can easily be used with gloves on thanks to the addition of string loops on all.
