Creators of the world's finest underwear, Zimmerli, offer up a stripped back simplicity in this basic pyjama top silhouette. But the composition is far from rudimental: a premium matrimony of wool and silk means this style is insulating and breathable at the same time. Styled with a simple crewneck and long sleeves, wear yours to bed or use it to layer when the cold snap hits.Zimmerli wool and silk blend pyjama topPulls onCrewneck, long sleeves, semi sheer, straight hem70% wool, 30% silkMachine washMade in Switzerland
