What a great item of clothing, so stylish and practical. Understated and yet elegant. I have several Seasalt waterproof macs, I specially like the ones with a fleece lining, and they are all brilliant. It would be great if the company could also design a longer midi waterproof mac, so that you can wear it with dresses. And some waterproof boots as well, please.

Not waterproof

My coat is not waterproof!! If I wear it in the rain, after 10 or 15 minutes water soaks completely through the coat at the shoulders, over the pockets, and several other places. So basically it only works as a raincoat in a light drizzle which defeats the purpose of having the coat.

sylish and practical

I love this jacket! I'm 5ft 2" and think it works well, I feel good wearing it, love the colour and also really practical, only a few slight niggles arms were a wee bit tight, and the double zip sticks a wee bit and the length of the sleeves are a bit long but that's cause I'm small.

I bought this mac for my daughter who lives in Berlin.
She loves it and we are both so impressed at the speed and efficiency of the delivery. To order it here in England and for it to be sent and received in a different country so quickly is amazing.

I was so taken by the experience that I bought a mac yesterday from Seasalt shop in Bristol.
Well done

lovely coat

Exactly what I wanted - a lightweight, longer mac with a nice unusual print. The material is beautiful, and although I'm tall, the arms seem long enough. It's a bit of an investment, but hopefully will last a long time.
