The best sun protection clothing in the world won't protect you hanging in your closet.That won't be a problem with this shirt.Aside from the uber-cool gradient fade prints they come in, you might think these are just ordinary technical shirts.

The key to great sun protection is choosing a shirt you'll actually use.
