And "moss stitch"?
I came across them just from a random Google search looking for jumpers I think. Leicester company, only use natural fibres so cotton, wool, cashmere although to be fair the alpaca socks I bought for my wife do have some nylon in them as well. Fairly classic styles and not silly prices. They seem to do pretty good sales, I had my eye on one of their heavy wool shooting jumpers but then the cotton version came up for forty quid so I bought that instead. The one I've just bought was in the sale, too.
The moss stitch gives a sort of waffly open texture, it's not heavyweight like a big thick ribbed thing. Midweight I suppose. This one's still a bit rustic, got big chunky seams where it's all put together. Be fine with a light jacket over the top for cold early spring days.
For fancy fine merino, John Smedley in Matlock is the place to go. They're more posh pullovers than chunky knits though. Prices are on the silly side but they do have a factory shop.
