I have just received a Seaman. I haven’t worn it in anger yet, but so far I am happy. It feels much more durable than Merz b Schwanen merino sweater it is replacing, however it is not soft to the touch (and may even prove to be a little rough on the skin).
As JDelage pointed out, the symmetrical neck feels a bit odd - although perhaps that will be handy if I am in a rush
The Seaman appears to be the right pick for me rather than the Sailor. The Seaman feels like a good thickness for layering with a coat or vest, and it packs down pretty well for travel (smaller than a hoodie).
I am very glad I sized down – as they are a Danish brand and have viking sizing. Although, I was a little surprised it is made in Italy, which isn’t a bad thing.
