Stylish all-rounders with a long history of success

The term 't-shirt' is pretty easy to explain: it's a top with short sleeves. Most of them have a V-neck or round neck cut and are made from light materials. However, this bestseller amongst clothes is much more than that. Since the 19th century, the useful features of this top have been worn as an undershirt. T-shirt manufacturers however were not happy with this item being hidden away and so set about making this top suitable as an independent item of clothing. The t-shirt has become extremely popular in the sports sector. It is now a standard item in every wardrobe. The range and choice of functional features have developed so much over recent years that they have become essential items of outdoor, sport and leisure wear.
