Long-sleeve undershirts for football
Long-sleeve undershirts keep you warm during cold training sessions.
Material of football thermal shirts
Many long-sleeve sports underwear shirts are made of polyester. Polyester is breathable and ensures that any sweat is wicked away immediately, so by wearing sports underwear you can prevent feeling clammy and your body getting cold from being wet. Polyester clothing also keeps its good fit and nice colour for a very long time, so you can enjoy your undershirt for ages!
Sustainability
Although you might not expect it, polyester is actually much more sustainable than, say, cotton. Besides the fact that polyester clothing lasts a very long time, it's also much easier to recycle than cotton or wool. That's why you can increasingly buy clothing made from recycled polyester, or polyester made by recycling things like plastic bottles!
