Lightweight, stylish and super warm!

This coat exceeded my expectations, its so warm and cosy and a nice fit. I haven't worn it in the rain yet so unable to comment on the waterproof element. Very well made, feels a lot nicer than a lot of coats I've had over the years. Its lightweight but very warm. Very happy with this coat!

Love it! It’s perfect. I am petite, I thought first that it looked big but now I love it! It’s comfy and cozy. The straps to hang it on the shoulders are very practical. I bought it as I was travelling this weekend to the Cotswolds, from London. It’s absolutely perfect!

Great Parka for pre-dawn bus stops!

Light in weight and super warm! The construction is well made, with thoughtful details (lined pockets, wind cuffs, and side zips) but it does seem a tad large. I opted not to size down, because I have some pretty sizeable shoulders and lats and this gives enough room for free arm movement, even with a jumper. I only wish it came in colours other than neutrals. I opted for black and will need to stick some reflective tape on the sleeves and hem. Maybe they could add that into the next design?

Used to come up large but they’ve amended the sizing for the new nimbus coats ( spoke to a lovely sales assistant in Nottingham store!) used to be an XXS in nimbus now an XS and I’m a size 10. It’s so nice, waiting for it to be cold enough to wear it!!

The best all around winter coat!

I had the old version of this coat and the new one is 100 times better. The zip on the original one was temperamental, this one is smooth as silk. It’s also now waterproof 🙌🙌. Amazing, warm coat cannot recommend enough

This coat is expensive! I toyed with the idea of buying it given the price! I’m on the sideline a lot and this coat it worth every single penny! I suffer with Raynauds and feel the cold- not anymore thanks to this beautiful warm coat

The warmest coat ever, and waterproof!

I already have a nimbus from about 2 years ago, its my go to winter coat which I wear from Oct - Feb without fail, for commuting, kids football watching from the sidelines and dog walks! I was so excited to see a waterproof version, and so pleased with my purchase! Def worth the money, I love that I can feel stylish and even wear for nights out, but also with all the technical attributes. It is a roomy fit but means I can put jumpers underneath for the winter days so Im happy! #teamsweatybetty

Have been looking at this for a couple of years and when I noticed it is now waterproof as well I grabbed. It is lovely and cozy without being bulky and heavy. Love!

Waterproof and Warm - THE best coat!

Originally posted on sweatybetty.com

I bought a Nimbus after having my eye on it for a few years and I am SO glad that I did. The quality is fantastic, the zips on each side mean that the jacket feels feminine whilst also keeping me lovely and warm. Every detail has been thought of, from the fleece lined pockets, to the straps sewn on the inside which allow for the jacket to be worn on my back. To top it off, the jacket is waterproof, meaning I am ready for whatever British weather comes my way! I love it!

Style and function nailed!

Love the new Nimbus - the waterproof aspect in a puffer jacket is a real win, keeping me warm and dry. Being 5ft 4", the double ended front zip and zips to open the side seams make this longline style work for my frame. I look good, feel great and keep dry. V happy.
