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.

Designed as a regular fitting cold weather jacket that can be worn with many layers, it also has the flexibility of being a great winter climbing/belay jacket due to the technical features and fabrics.

  • Over or under helmet hood with Lycra binding
  • YKK® VISLON® front zip with insulated zip baffle

  • Elasticated lycra cuffs
  • Hem drawcord
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.

Looks smart and very comfy

Practical and smart

RAB, it seems has got it sorted with this. Down jackets are brilliant until wet. Synthetic gives all the positives and more, no apparent down (no pun) side. Stuff sack pocket, great idea, watch the stitching at the top of zip... Ink/mimosa, good combination, as when it goes pear shaped, as it does sometimes, turn jacket inside out for high visibility in emergency...

Rab jacket

Bought this jacket for my partner, he loves it! Looks absolutely great, really good quality, lightweight does exactly what it says keeps you dry, toasty and keeps the wind out. Highly recommended.

Great jacket very warm, did get caught in a downpour in it but even though the jacket was soaked I still remained warm. Comfy, great fit and perfect for a cold dry walk

Great Jacket

Bought this as I have an allergy to down and it’s superb. Worn it all weekend in the lakes with freezing weather and really warm and wind proof.

Great price and the no fuss price challenge made it even better value.

Great jacket!

Purchased this jacket about 6 weeks ago and got it at a decent price of £139 and then 10% military discount. The jacket is light, warm and breathable and extremely comfy. I went for the dark blue which I thought may be a little too shiny at first but I do love the colour! All in all a great jacket and a bargain at the price :-)

Rab Nimbus Jacket

For many a year I have worn North Face as my first choice for a winter coat however this year i decided to buy something new.
Go Outdoors had a sale on advertised through their magazine which prompted me to check out the latest jackets in store.
I liked the look of the Rab Nimbus jackets which gave choice of colour and style. The jacket is so lightweight and comfortable to wear..i did sort of wonder if it would be warm enough given my current jacket is filled with down. The Rab although made from complex man made fibres is very warm to wear without the need to have lots of base layers underneath. I also opted for the fixed hood instead of just collar as this catered for all weathers. Very satisfied with purchase and would recommend.

Drawcord snaps

Absolutely shocking quality! I purchased a nimbus coat and have had to replace it TWICE in under 24hrs as the hem drawcord comes away from the inside of the coat if you even think about tightening it let alone actually tightening it!
Will not be purchasing another Rab product ever again!

Brilliant jacket. I bought this for day to day lightweight wear, didn’t want bulky but did want warm and especially wind proof.
This fits the bill exactly. Very comfortable, deep pockets to keep gloves (flat - not balled up making it the jacket look all out of shape)
Hood is easy to put on quickly and moves with you so you can actually see when you turn your head, hood on or off the jacket zips up high and keeps your neck warm.
One minor tip, the zip can snag on the material either side occasionally, if you pull it slightly away from your body when zipping it solves it.

Very good jacket

This Rab even though at the bottom of the price market is a great jacket, a very good fit and very good at all temperature with correct layering of clothes. I’ve worn this in the U.K. and in Norway skiing when the temperature has got down to -18 and I cannot fault it.

Rab Nimbus

Comfortable fit with good pocket space. . Lightweight and proving effective in light rain. Pleased I tried on before purchase, as I needed one larger size than normal (esp around the shoulders).

Great Jacket

Good price, this jacket is super comfortable, extremely light weight and unbelievably warm,
Can be stuffed back on itself into one of its pockets to shrink it down if it needs to go into a pack. Its waterproof enough for most conditions but beware for rips n tears as its not designed to be a hard shell.

Overall a great jacket and great addition to my gear.

Rab men's Nimbus Jacket

Just been to Kiev and survived temperatures of -6 with this jacket and correct layers underneath. Warm all over, especially around the chin and neck area where the cold can get in! Bargain at this price

Great Jacket

Really good jacket, very insulative. I found that it fits fairly true. I am 6' 2'' and got the large size, fits nicely around the chest and good length in the arms.
Good level of water resistance and well wind proofed. Really nice all-round jacket
