IR is heat and is at the long wavelength end of the visible spectrum. UV is ultraviolet and is at the short wavelength end of the visible spectrum. Your pants must be insulated and your shirt is not. Your pants are basically about the same temperature (heat) as the surrounding grass. You can't see either UV or IR. Some compounds absorb UV which you can't see. They then emit light at a longer wavelength which you can see. The difference in energy is given off as heat. UV is high energy while IR is lower energy.
