Fully waterproof, windproof and breathable.

A cosy raincoat designed at our studio over looking Falmouth Bay. Our River Sea Coat is made from cotton-rich waterproof fabric with a soft, peachy feel and subtle herringbone texture. The upper body is lined with Wellsoft® fleece, while the lower body is lined with quilted polyester for a soft and cosy feel, adding warmth without bulk. The sleeves are lined in polyester, so it’s easy to slip on and off featuring three poppers on the cuffs. Finished off with a two-way zip closure and poppers for a clean front, two patch pockets with popper closure and an adjustable hood with a tonal cord. Just add a pair of Seasalt wellies and you’re ready for anything the weather has to throw at you.


Inspired by traditional oilskins, our unique Tin Cloth® coats and jackets are crafted from hard wearing natural fabrics finished with our high-performance waterproofing treatment. The result is a waterproof, windproof and breathable jacket with a soft yet durable finish.

Nice coat

The colour mahogany is just lovely. I tried hard to love this coat, it seemed a bit too roomy which was fine,, but for me , not much space across the back round the underarm. The fit was not right for me, sadly I returned this.

lovely coat

This is a well made coat and I loved the colour. However, it was too big (size 14) so have exchanged for a Plant Hunter coat in a 12, which is roomy enough for an extra layer and longer.

Great Coat

Bought my Mum the full length coat and she absolutely loves it, but as a driver wanted a shorter coat and this coat was perfect. I absolutely love it, no more wet shoulders for me!

Love. This. Coat.

Whether I am cycling through rainy weather or going for a walk on a cold morning: this jacket is sure to keep me warm and dry. Makes going outside in Dutch Autumn weather so much more fun and appealing. Usually I am a size 38/40 (10/12), but the website advised me to get size 42 (14). It is a bit big for me, but that's actually kind of nice because now I have space for a thicker jumper when Winter comes around. The hood is soft and snug, doesn't blow off in the wind and also fits with a beanie underneath it. Never before did I look forward to cold and rainy days ^^
One thing I have to get used is that the collar pushes against my throat a bit when I am not wearing the hood. I think the hood pulls the collar back. But that's a small detail.

River Sea Coat

Brilliant coat just what I wanted warm and very comfortable. Just one thing the sleeves are a bit long but have turned them up so not a problem.

perfect just what I wanted

we went up to the north york moors in october, I had my 'performance' walking jacket my daughter had her seasalt coat - guess who kept drier and warmer! I ordered this coat as soon as I got home & I'm very pleased. It fits well, I love the mahogany colour & the fabric is soft. My first seasalt coat & I'm wondering why I never bought one before

Sister very pleased!

This was a gift for my sister and she is delighted... There is a real quality feel about it and it really *is* rain and wind proof... Nice and snug and an easy fit. Excellent buy!

Perfect fit and colour. Very warm too. Great for hiking. Material is a bit stiff, compared to the Janelle, but maybe through time it will relax.

Even tackles the Baltic rains!

I bought this coat as an autumn coat in preparation for a wet, Tallinn autumn and I have not been disappointed. I just walked 45 minutes in the heavy rain - warm and cozy as ever! I really recommend this coat!

A nice dog walking coat

I already owned the Janelle size 14, but after losing weight I could wrap the front half way round my body. I checked the size chart and size 12 in the River Sea coat was recommended. However, on wearing it, I find it is snug on the chest but much to roomy round the middle. I think I would have managed a size 10 in the Janelle. The sleeves are just the right length and the hood is much better than the Janelle - coming forward further and protecting me against the rain and wind. My concern is that this tighter style will not allow for layering in the colder winter months. I would love to see a winter coat with quilted lining in the sleeves and a less flared style that the Janelle.
