Nimbus Waterproof Longline Puffer Coat

I bought this coat in November 2025 and so far it has been amazing. It is extremely warm and cosy. I have been out in a few downpours and it has been totally waterproof. I do agree with some of the reviewers that it is very bulky and puffy when you sit down however, if this is what it takes to ensure it is so warm and waterproof then it is worth putting up with the bulk.

Lovely coat and have enjoyed wearing it only in the coldest weather for past two years. I bought it as an investment jacket as it is expensive. However this winter the zip has jammed and will not work, making it unwearable. I requested help from SB with a repair, but as the coat is out of warranty, SB said they were unable to help me and they do not offer repairs. I have tried to get the zip repaired independently but this is not possible due to the factory colour and design of zip. Such a shame and very disappointing.

I have always wanted a Sweatybetty coat, and finally this year I treated myself and got one for Christmas. On first impressions it was great, warm, snug and waterproof. However I now discover that you cannot sit down in it, the puff bit is full of air and it feels like you are sitting on a balloon. You certainly cannot drive in it. I would have returned if I could, but unfortunately had worn the coat before realising this. Very disappointed, and a very experience mistake. So sad.

Be warned … This coat is BIG ! It is so warm and cosy and really well made. I’m really happy with it

I had my eye on this coat for quite a while and then I saw it was reduced on Cyber Monday so had to order it. The quality is exceptional,it has features that I like (double zip/side openings). And waterproof which is rare for a puffer. I absolutely love it.

I bought this as it’s waterproof and warm ! Wore it to a footy match and was toasty

Bought this so I have no excuse not to get out for a walk every day. It is warm and waterproof and has fleece lined pockets. The side zips at the hem are useful when striding out and sitting down. It does get puffed up with air so when you first sit down it but it doesn’t take long to deflate! I bought it at a Black Friday price which was quite the deal.

Waterproofing is yet to be put to a tougher test but has been good in light rain. Despite being lightweight, this coat is very warm and the fleece-lined pockets are lovely. To make this coat really worth the price tag I would suggest the hood be fastened around the neck to make it more flattering and to reduce the draft. Some slip in pockets for hands would be useful that the zip doesn’t need to be undone to pop your hands in. And, as another reviewer has said, branding or a badge on the arm would be a nice touch although the subtle look is useful for work. HOWEVER I feel physically sick that I have wasted so much money on this. I have genuinely worn my coat 3 times and it hasn’t gone totally and utterly flat on the bottom. Of course I wear this in the car so sit on this part but I WILL NOT be wearing one coat for driving and then changing on arrival. Customer Sevice have suggested that I privately get a repair specialist to look at this. Perhaps after one season of use I might consider this but I WILL NOT be doing so after literally one week of use. INSANE! I have attempted to puff up this section of the cost but nothing works. I feel so sick that I wasted so much money on this coat, that i have wanted for some time.

I’m a size 12, 1.64 cms and the coat is a grew fit and looks fab! Have only rated it three stars due to the sparse hood. It barely covers my hairline and when I was caught in a rainstorm, the rain was pouring down my face forcing me to bend forwards as I walked. My last, similar style coat, had a large hood that protected me from the elements. Very disappointing. I would have not purchased had I realised that functionality was compromised.

Had to leave a review after being caught for over an hour in heaviest rainstorm I’ve known in years. Coat did it’s job and left me dry and cosy. Otherwise lovely quality, lots of little details. Was initially unsure about the length looking at the tall models on website but perfect midcalf for me at 5 ft 5- very happy

Lovely and warm and its waterproof claim was put to the rest this weekend and passed with flying colours! Def size down tho it’s on the bigger side.

Love my new khaki green coat, very warm and comfortable. Cannot confirm how waterproof it is yet. I am a size 12, 157cm/5`2" and bought the Small size which is perfect with a couple of layers underneath. Length comes to mid calf which I love, makes it nice and cosy, with side zips if you need more space when walking. Lovely roomy hood and warm fleece lined pockets. I appreciated the little inner pocket. If anything, a smidgen more room under the arms, but not a problem as it is. Very happy and would buy again in future in a different colour. Shame the price is on the higher end, but hopefully will prove a good investment.

This coat is amazing! It’s like wearing a duvet. It’s waterproof, comfortable and love the zips at the side or the bottom to give more movement. Just love it

Lovely coat but zip broke and can’t be replaced which is rally disappointing
