If a prayed with a breathable sport t-shirt that have tiny holes in it of the size of a needle in 3 bands on the shirt, so the holes are many as they are all along the bands. Are my prayer valids as I thought they are negligible? Now I'm doubtful, if not how to make them up as days have passed?

Ustadh AbdulAziz al-Haqqan
A man’s awrah is from the navel to the knee, and Imam Ibn Baz said a thin garment does not invalidate a man’s prayer if trousers or a lower garment cover what is between the navel and the knee.
