Purchased a sun shade to wear on my hard hat for working outdoors in the gen yards of data centers. Installation was a breeze, the shield is very durable. Rigid enough to take your hard hat off with but limber enough to knock into stuff and bend versus getting hung up on it. I abuse this thing, even in the rain it holds its shape and was suprisingly good at keeping the water off of my face! I highly recommend; very tempted to buy another one to have some variety lol
