Abstract: An adjustable garment that forms a hand sheath with at least one fingerlike extension, and operable to adjust in length through various means for providing various amounts of protection to the hand against radiation. The adjustable garment includes a body portion configured to be operable to at least partially cover a hand. The body portion includes a body proximal end and a body distal end. The body proximal end includes a body aperture configured to at least partially allow a hand to pass through. Each extension can be manipulated, pushed, or pulled to expose additional areas of each finger. For example, a lateral force presses the extension proximal end towards the body portion, thereby at least partially exposing the at least one finger. The lateral force pressing against each extension serves to deform the size and dimensions of the flexible extension to deform, stretch, or twist.
