He will still need to wear a vest, and his T-shirts can now be put back into circulation.
However, please be aware that the weather can still be volatile, so if it is a particularly cold day, you might still feel he needs the thermal leggings; so feel free to exercise your own judgement.
Also, if Fela is sweating a lot, he may need to remove some clothes. If it's a very hot day, the fans are also available for use.
Thank you for your co-operation!
