Abstract: A solar radiation arm shield includes an elongated C-shaped substantially rigid shell of a preselected material with a predetermined interior partial circumference defining first and second end edges and first and second side edges. There is a first adjustable releasable attachment strap with separate engageable portions fixedly attached to each of the first and second side edges proximal the first end edge for removable attachment to a wearer, and at least one additional releasable attachment strap has portions fixedly attached to both the first and second side edges.
