Here are few reasons why polyester sports jerseys are more popular than cotton sports jerseys. Many people often wear sportswear as regular wear. Cotton absorbs moisture but does not dry easily. Synthetics like polyester do not absorb moisture but help in swiftly transporting it to the outer surface, from where it dries off easily. We have officially started the age of "Athleisure" apparel, activewear that's not really worn for sweaty exercises. Women aren't always purchasing these outfits with the purpose of hitting the treadmill or yoga mat. They're usually wearing them because they're comfortable, beautiful and gives them confidence in themselves. Cotton tends to absorb sweat and while this is fine in a regular environment, but for a sports person who sweats copiously, the garment will become wet, sticky, and uncomfortable. If you don't sweat a lot or if the environment is quite cool and well-ventilated, then cotton may be more or equally comfortable. Polyester is the only most popular fiber employed in sportswear. But polyamide, polypropylene, acrylics, and elastane are also employed for activewear. The material utilized in sports jerseys needs to be both breathable and stretchable.

It should be capable of sustaining the heat balance between the excess heat generated by the wearer due to enhanced metabolic rate, and the capacity of the clothing to disperse body heat and sweat. As humans moved forward and their thoughts became more modest and as our technology to manufacture clothing improved, we were able to make clothing to accommodate the other related factors like climatic and environmental. Most people have a consistent weight and build unless they are actively trying to lose or gain mass. Most people have consistent body measurements and benefit from tailored clothing. Weight (while diet and exercise are consistent) only fluctuates up to 5 pounds, and that doesn't necessarily affect the fit of clothing. You see there are different factors involved in designing functional clothing such as a sports jersey. • The fabric requires to be capable to hold throughout the span of the exercise and support the security of the user. For instance, cotton clothing does not have any elasticity. This leads to restrictions in movement and also it can't hold good against the harshness of the sports environment. • The fabric is good under a hot climate where the sweat is transferred through capillary action to the fabric surface and sweat evaporates. But the conditions for a sport are not always cold and also the metabolic rate, the sweating rate is not the same as normal conditions. • Polyester, on the other hand, wicks away the sweat from the surface faster in high metabolic rate sports and nowadays we see dry-fit which efficiently keeps the sports person dry.
