The crewneck is ten-ply, which means it is preposterously thick. Wear one and it'll feel like summer no matter the true climate. It is hand-framed — i.e. made by a single skilful knitter, who controls the quality and tension of the stitch on an old and hand-operated contraption. A true rarity, this, these days.
The crewneck can make another boast in the world of luxury-grade knitwear bingo: it is fully fashioned. That is to say, the sleeve and body are individually shaped and engineered — just like a tailored jacket, say — to achieve the best shape. This is not ordinary; it demands knitting expertise of black-belt standard.
The density of the crewneck, comparable to heavy seafaring gear, does not come at the expense of comfort. See, it is made with superfine lambswool — 1/14 Nm, to be exact — and is cosy and comfortable to an incomparable extent. If one were prone to superlatives, it could be called sumptuous.
The back of the body and the sleeves are thinner than the front: they're six-ply, compared to ten. The thinking is that this frees up some space for wearing a jacket or coat over the top. The sleeves are also raglan, which means no shoulder seam, which means even more space and freedom of movement.
It is hand-linked — i.e. body and sleeve, or sleeve and cuff, are not stitched together. Instead, the tiny knit loops of each part are linked together, with a knitting needle, by hand. Painfully slow work, as you might imagine — but the only way to achieve a soft, seamless finish. The seam here, for example: where is it?
The neck, hem, and cuffs of the jumper are all rib-stitch, which keeps them nice and tight. The cuffs are turn-back: twice as long as usual, so they can be turned back on themselves. It is a nice thing to play around with — and useful, too, in that the sleeves can be shortened or lengthened at the behest of the wearer.
There are three shades of yarn at play here — one black, one dark grey, and one light light grey. The yarn is knitted into a tuck-stitch, which has a layered, textured appearance. It is dense, on the one hand, but springy and breathable on the other. And just look at it — marvellously textured, the tuck.
