Fully waterproof, windproof and breathable

This gently fitted, mid-thigh length waterproof coat has all the practical details our coats are famous for - a cosy high neck, flap pockets, adjustable hood and drawstring waist. It fastens with a two-way zip, hidden by a popper placket. Perfect for layering with a cosy jumper on chilly mornings.

This coat is made from our new, waterproof Tide Cycle® fabric.

Tide Cycle® is woven from recycled polyester fibres, made with used plastic bottles. It’s waterproof, breathable, hardwearing and extremely soft to the touch.

Great coat

Originally ordered size 12 but as añother review stated arms came up quite narrow. Returned and managed to order size 14 which is perfect . Doesn’t make you feel like sack of potatoes as drawstring waist means you can “tailor” it to fit . Only criticism would be that you don’t have a means of email when back in stock - means you just have to keep checking web site and hope for the best ., which is what actually happened for me

Perfect apart from hood

Lovely coat and so nearly perfect. It was a little tight across the shoulder/chest so a bigger size may work better. But the reason I have to return is the enormous hood. It is so big it comes down an inch below my eyes, not great when I am planning to wear and walk in the rain. Such a shame as otherwise a lovely coat.

Porth Mellin Coat size 10 Regular

I had been looking at this coat for a few months, and took the plunge and bought it a couple of weeks back. I am very pleased with the coat, and it has already bore the brunt of the Welsh weather, and I remained dry!
I am 5ft 2in, of medium build, so bought the size 10 regular fit. The coat comes to just above my knees, so the top half of my legs don't get wet. Plenty of good sized pockets. Easy to wear.

After hearing such good things about these coats from family I decided to give this one a go. I am 5’4 and 8st, I ordered a 10 after reading the fit was on the small side as I like to have a bit of room to layer when it’s colder.
Coat came in good time and I really liked how no plastic was used, the coat seemed well made and I was pleased....until I put it on. Wow! The upper arm/shoulder area was so tight I couldn’t even lift my arms past horizontal position. I have a small chest and my shoulders are not broad so I’m confused as to how it’s supposed to be a size 10? (For reference my tops are usually a 6-8.)
The next size up would have been far too big everywhere else so I’ve had to return it and look somewhere else :(
Can’t fault the company, great service and it was a lovely coat which is why it’s all the more disappointing for it to not fit.

Porth Mellin Raincoat

I am extremely happy with my new Porth Mellin raincoat. It is both smart and practical. I used the Size Guide which advised a smaller size than I would normally chose and it is a great fit on me. Thank you Seasalt.

Perfect lightweight waterproof

I’ve been looking for a nice lightweight waterproof coat for a while and this one is perfect! I can wear it over a chunky jumper without being too warm and it also has loads of pockets inside and out which is great. The big hood fits over a woolly hat. Just right for a wet autumn walk like today. I’m 5’3, size 10 and the normal length is fine, although comes up longer than on the model pic. The coat has quite a slim fit, but I like that.

Wonderful coat, super duper waterproof

This coat is fabulous. It fits perfectly and it is very waterproof! Especially in the Cornish rain, which is very intense! Im extremely impressed so far. I hope to stay nice and dry this winter.

Recycled Polyester Tide Cycle

Inspired by our love of the sea

Our innovative coats give new life to plastic waste

Tide Cycle® is woven from recycled polyester fibres made with plastic bottles. It’s waterproof, breathable, hardwearing, easy to care for and extremely soft to the touch. Production requires less energy than virgin polyester and it helps reduce the amount of plastic heading for landfill and our oceans.

Tide Cycle
Tide Cycle

Single-use plastic bottles are collected and broken down

Tide Cycle

The small plastic particles are then re-spun into polyester fibres

Tide Cycle

These are then woven into the Tide Cycle® fabric we use for our all-weather coats.
