¿Has explorado la oferta de Brooks Brothers?
Desafortunadamente, por mi IP solo me sale la página de USA, sin embargo debe de existir la equivalente en UK.
En España, entiendo que en el Corte Inglés distribuyen la marca.
Creo que algo así es lo que andas buscando:
"This crewneck is the perfect three-season weight. Crafted from 2-ply 100% Supima® cotton. 9-gauge. Ribbed detailing at neck, sweep, and cuff. Soft hand feel. Machine wash according to care instructions for best results. Imported".

Este ya es de otra calidad y rango de precio:
This ultra-luxurious cable crewneck sweater is crafted from a cashmere and superfine silk blend spun in Italy. As part of our 3-D Knit Collection, it has been fashioned as a single, continuous garment, rather than assembled in panels. Without seams, it offers an improved fit, greater comfort and increased durability. 50% cashmere, 50% silk; dry-clean only; made in Italy.
