Mr Calvin Klein said "It's so modern to be comfortable... to wear something that's easy" and this soft cotton-blend jersey T-shirt captures the ethos of his eponymous brand. Streamlined and breathable, it is ideal worn as a base layer or when unwinding at home. Team it with classic boxer briefs. Shown here with Calvin Klein Underwear boxer briefs.
