NEW YORK – A video showing a straphanger taking off his shirt right off his back for a man-in-need is going viral.

The man is seen taking off his white T-shirt and helps put it on the shirtless man on a Brooklyn-bound "A" train.

The recipient was shivering and this subway rider gave what he could to keep him warm.

Left in just tank top, the do-gooder also brought over a knit cap and put it on him.

The person who took the video recalls the Good Samaritan asking the man if he needed to go to the hospital.

It is unclear what happened after the video ended.
