31% acrylic, 22% polyamide, 18% wool, 15% viscose, 8% mohair. 6% elastane. Brushed knit fabric. Ribbed cuffs and hem. Full buttoned fastening. Regular fit. The Signal Cardigan is a understated but certainly very luxurious bit of knitted schmutter made from a blending of all the best fibres money can buy and reinforced with elastane to prevent any unwelcome stretching. Nowt to dislike about this one.
