Mainmast coat

Love this vegan parka! Extremely silky smooth on the outside, keeps you warm.

Great apart from the zip

Although bought in October, I've just started wearing it. I love the look and the feel but the zip is such a problem. I had to return the first coat because the zip was completely stuck. The zip of the replacement sometimes decides to work and sometimes doesn't, depending on the mood it's in....Not good when you're in a hurry on a cold wet morning. Looking at the reviews, I'm not the only one with this problem. I expected better of Seasalt.

Mainmast coat

Although the coat fitted perfectly I had great trouble doing up the zip, so decided it wasn't for me and had to return it.

Dear Chihuahugirl,

Thanks for your review of the Mainmast Coat, we're sorry to hear that the coat wasn't perfect for you.

We do use YKK double zips on the Mainmast coat which some customers find a little tricky at first, the key is to make sure that both zips are lined up and click into place at the bottom before pulling the first zip up the coat.

This also gets a little easier the more you pull the zips.

Best wishes,

Loved this coat so much I ordered the other colour! I like the lightness and the fitted waist.

Not the usual Seasalt quality

I ordered this coat in both colours as my local store (Southwold) did not hold stock. This review is for both. Disappointment is an understatement, they both had sewing faults - stitching broken & the elastic round the hood was caught in the stitching, so it would not draw up.
As the design does not incorporate an internal collar there was a strange gap when the coat was fully zipped. Pockets were unzipped and with no 'warm' lining.
Other Seasalt coats I have, have the internal stand collar, zipped pockets etc. and they are much better.
Both these also exhibited an odd trait, the bottom of the coat rode (ruched) up in an odd way as if the lining and the material were 'fighting' each other. Does anyone remember Austrian blinds!
Positively the material and general style were lovely, please try again, I would happily pay more for the perfect coat. I know you can do it I own lots!
