A crew neck jumper has a round neckline: the most classic piece of knitwear there is. Men's crewnecks go over a T-shirt, a polo or a shirt, so they work with almost any outfit.
Merino wool for every season
Profuomo crewnecks come in merino wool, among other yarns. Merino is soft, breathable and light, so you can wear a crew neck from autumn to spring.
