Knitted Pyjama Trousers are based on the long-running woven pyjama trousers, with no side seams, a single back pocket, cross-over fly and drawstring. The size label sewn onto the back of the waistband stops the draw cord from pulling through.

The lambswool yarn is knitted ‘greasy’ (dyed but otherwise unfinished) and then cold felted. Each piece is knitted around double the finished size, and shrinks during felting.The practice of felting wool fibre in cold water is older than weaving, spinning, or knitting, and knitwear has long been felted to increase its density and help protect against the wind. Unlike hot water felting, which matts the fibres together fully and creates a stiff fabric, cold felted knitting remains light and stretchy while being beautifully thick and soft.
