Cardigans differ from their sibling the sweater thanks to the fastening at the front which is either a zip or buttons. This makes the cardigan more comfortable and wearable and allows it to be worn in combination with an undergarment. Men's cardigans make a return with versions that are more classic, warmer and hard-wearing, although there are also options for those looking for something different. Proposals from brands such as Brunello Cucinelli, Fedeli and Loro Piana include knitted men's jackets made mainly from wool, although there are versions with mixes of wool, cashmere and silk, pure new wool or alpaca wool and even cotton. The cardigans range from plain knit, to cable knit, and also rib knit or jacquard. For those looking for something warmer, there are also men's cardigans with inner lining.
