Rome, January 4 - For Norwegians, the word 'Koseling' (in English 'cosy') signifies the feeling of intimacy afforded by staying at home during long winter afternoons in the company of friends and family, snuggled up in front of a fire and dressed in comfy jumpers made of thick wool, feet thrust into fur-lined boots. This philosophy of life combats the laziness and depression that can accompany the cold season - and it includes wearing the right clothes. Even at lower latitudes where winters are typically dryer and milder, the days are still shorter and the cold can dampen the desire to go out, with the result that the mood of inhabitants accustomed to months of sea and sunshine inevitably takes a turn for the worse. A scientist spent a year in northern Norway - where January temperatures plunge to well below zero and snow lies several metres deep - in a bid to discover the secret of the happiness of people living in Lapland. He discovered that Nordic populations face winter not as a punishment but as a period to be enjoyed to the utmost - including through attire. This year the trend is extremely strong, despite record high temperatures to date, and the mountain look appears to have conquered urban areas as well. The jumper is the basic element of Koseling Style: classic or deluxe, in cashmere or fine wool, it is able to withstand even the severest cold, and every designer or label has at least one pullover or cardigan in their autumn/winter collections. Cashmere is the most popular material, as shown in the output of Laura Biagiotti and Brunello Cucinelli and also of more affordable brands such as Japanese casual wear label Uniqlo. However, ordinary wool that has been softened using silk or viscose is also in. Typical heavy Norwegian-style wool jumpers are popular among young people for wear over smooth velvet or corduroy trousers or eco-leather leggings. Turtleneck or round neck jumpers are also a hit, in classic neutral tones such as white, black or light beige, but also with brightly coloured geometric and abstract designs. The cult London label Mou and the classic Australian UGC produce the soft, warm boots typical of footwear 'Koseling style'. Fur hats, snoods, earmuffs and cuffs complete the look.
