There is no doubt that tracksuits are no longer a sports accessory but rather an essential piece of kit. When football teams are training they now wear a training tracksuit that defines the team image and sponsorship, if any. This applies right across the sporting spectrum, from team games to athletics. At any field and track meeting the competitors will all be wearing tracksuits when they are not actually competing in an event.
The same applies to football teams who are more often seen in their tracksuits than their football kits. We could cross reference this against any other sport and the same applies. The popularity of tracksuits as essential sports kit is unquestionable and they must rate as the most desirable piece of sports kit on the market bridging all sporting disciplines. As regards professional sports teams, especially football teams, their tracksuits are also a vehicle for branding and sponsorship promotions so are treated as respectfully as the kit in terms of image promotion and marketing. In practical terms track suits provide effective clothing for training sessions as they are warm, waterproof and aerated.
Outside of the sporting world there are growing numbers of ordinary citizens whose preferential clothing wear are tracksuits. For whatever reason people are buying tracksuits as general clothing and for many they are a fashion statement. The walking fraternity who buy tracksuits are less concerned with style and design than comfort. For them the tracksuit is a functional clothing item they require comfort, flexibility and rain proofing in their tracksuits and are less concerned with fashionable looks though you cannot discount some degree of this consideration when purchasing the clothing. Almost all tracksuits that you might view either on line or in sales catalogues are attractive from every point of view; they are well designed have intricate colour combinations are styled fashionably and are reasonably priced. They can be imitation copies of football team tracksuits or bespoke one off tracksuits. The one common feature is that they look very good and represent excellent value to the consumer whatever reason they might have for wearing a tracksuit.
Tracksuits have become more of a fashion icon since celebrities have been filmed wearing them socially and not just for jogging and exercise activities. Even politicians have been photographed wearing tracksuits. This all suggests that they have become socially acceptable as every day clothing wear and rate highly as fashion icons as well as essential sports wear.
