Cotton or polyester?
The trade-off
In a cotton t-shirt, your sweat stains are immediately visible, but polyester gets smelly faster. We already knew that, but now there is also a research team that has looked into it. After an hour of spinning class, 26 t-shirts were stored for 28 hours. Bacteria grow faster on polyester, causing foul odors to develop faster.
Don't panic
You can continue to wear polyester sportswear without any worries. As long as sweat does not come into contact with bacteria, it is odorless. If you wear a clean shirt and don't keep it on too long after exercise, there's probably nothing to worry about.
Which do you think is worse:sweat stains or sweat smell?
