Fab jacket

I love this jacket, not tried it in the rain yet, but looks very smart and stylish on my slim shoulder and hip, with big boobs and belly body shape, very happy with my new raincoat

Beautiful, but....

I love this jacket but the sleeves are so long on me, very disappointing. Also the colour was not to my liking. I might reorder in different colour and get the sleeves shortened. Otherwise this is a beautifully made jacket in a quality material. I’ve never tried petite before but at 5’3” perhaps I ought to start trying.

Mum laws really pleased

Ordered for my mum who doesn’t do online shopping
She wanted the black and the red colour. She’s between a HS 18 to 20
I ordered the size 20 as she like to have room to wear a jumper underneath, I had them delivered to her address and she was really delighted with the quality of the coats and was very happy with the fit.

Simply perfect!

After getting the Plant Hunter coat for Christmas (and absolutely falling in love with it!), I realised as the weather was getting warmer I needed a shorter, lighter coat for our ‘British Summer’! The Lagoon jacket is perfect! With the same great level of waterproofing it is great for when I’m out and about and get caught in a downpour! Fit is great too, with the drop hem at the back providing extra coverage. I went for the mainsail colour which is more muted than I expected but equally lovely! So, so happy with my purchase- thank you Seasalt!

Great waterproof jacket

Love this waterproof jacket. I bought the coat version last March and have had such great wear from it through all Spring and Autumn, so bought the jacket version for Spring and Summer,

Great coat, great fit, definitely windproof. Haven't had any rain yet but I'm confident it will be waterproof too. I like the inside pocket for my phone so I can go walking without taking a bag.

Spring jacket

Well made shower proof spring jacket, just right for walks. Has a slightly padded lining so should give a bit of warmth. I'm looking forward to wearing it this coming weekend - its warmed up a bit now so it should be just right for our first day out for ages. I'm only 5'2" so it fits nicely, ie not too long.

Great Jacket

I absolutely love this jacket! Originally ordered in my usual size (12) but, as I am only 5' 1" tall, it was too long and wide across the shoulders, even with a jumper underneath. Returned and order a Size 10 which fits perfectly. The sleeves are quite long, even on the tightest setting, so they will have to be shortened - pity the jacket isn't available in a Petite fitting, but I would still recommend it!

This is just perfect for walking. Excellent fit all round. Fits well but room for layers on chilly days. And I like being able to detach the hood. Very well made.

Great jacket

Wanted something waterproof and lightweight for Spring weather and into the Summer and this is perfect.

I'm a tall 14 with curves and was worried it might be a tad small but if anything I think I could have a gone a size to a 12 but I wanted to be able to put a hoodie on under the jacket for colder days and a 12 wouldn't haven't allowed that.

Love the style of the jacket and how it hangs and the striped hood which is detachable is a nice touch.

So pleased this came up on my Next search so I ordered direct and it came within 2 days.

Great service and great jacket.

Thank you Seasalt
