A quick drying, featherless synthetic insulated jacket, keeping you at your best when out in the cold.

Ideal for winter walking and damp conditions, the Rab Nimbus Jacket is made with a lightweight insulation that combines almost all the key benefits of natural down and synthetic fillings, whilst avoiding their limitations.

Cirrus™ powered by 3M Featherless insulation

Cirrus™ is a new, breakthrough insulation that combines almost all the key benefits of natural down and synthetic fillings, while avoiding their limitations. Technical, water resistant fibres are expanded into a “down-like” structure, to create a cloud of warmth. Cirrus™ has been extensively tested in development to deliver the same warmth for its weight as 600 Fill Power duck down.

Unlike other synthetic insulation it lofts freely to trap warmth. It compresses well when packed and is robust and durable. Its resistance to moisture, warmth when wet and speed of drying are very high: superior even to Hydrophobic Down and previous man-made insulations. Powered by 3M Featherless technology.

Simply Brilliant!, 17 March 2017
By Andy
Can't recommend this highly enough! Superb fit and quality. So warm! Looks great. Feels snug. Wore watching football for 90 minutes outside in continuous wind and rain. Kept me totally warm and completely dry. Jacket dried within 10 mins of coming inside. Ultra light - you can forget you're wearing it. Well done Rab! A very happy customer!

Great jacket, excellent value, 29 October 2016
By CamdenRocks (London)
Purchased the "Ebony Grey" size XL. First of all, it isn't dark grey, as the description suggests, it's navy blue. Other than that the jacket is well fitted. Slim, but not tight. Great when worn alone or as a mid-layer under a shell. At the discounted price it's a steal.

Great For Packable Lightweight Warmth, 06 December 2015
It was a tough choice between this and the Rab Alpine micro down jacket but this one won as the synthetic insulation was more durable in wet UK conditions.
The jacket is warm, light and squashes down nice and small. The inclusion of a hood and the slightly longer cut around the backside make a lot of difference, much warmer and more comfortable in the wind than the higher cut jackets with no hood.
A great bit of kit to have in your pack for rest stops, or emergencies, as well as in colder weather.

Exactly what you expect, 09 November 2015
By Rob (Wigan)
It's hard to fault this jacket, it does exactly what it says it will. The main reason you would buy this jacket is for the warmth - and it definitely delivers in that respect. Another benefit is that it folds into itself (though the left pocket) so it's easier to store. It doesn't crease either.

There are a couple of things that it's worth bearing in mind. I ordered the black jacket online, when it came it's actually not black, it's more of a pearlescent blue. It's nicer than black anyway!

As it says in the description, the jackets is not waterproof in any way, it's not even splash proof.

The jacket doesn't come with any bells or whistles, no fancy pockets, velcro or adjustable cuffs but it's something you can see wearing for years to come. As it isn't down, there's no feathers popping out of it which is a bonus!
