Please ensure he wears these whenever he is going out to sweat as they will NOT absorb the sweat as the cotton ones do. They will therefore keep him warmer and help him to avoid discomfort and chills.
The M&S white cotton vests may still be worn when he is going out but ideally not for exercising. They can be tucked in neatly under an overshirt because they are not too long.
The long, loose cotton vests are best worn to bed in the summer during heatwaves or under shirts if Fela is lounging at home.
Thank you for your co-operation!
