OverviewThe Wiley X P-17 is one of our longest running and most popular sunglasses. It may be because of the low profile frames, or that it meets the ANSI Z87.1 safety standards for optical quality and high mass/high velocity impacts. It could be the high level of comfort from the light-weight design that somehow manages to block out all peripheral light. It's also possible that for over ten years we've been making constant improvements to an already trusted product. We're not exactly sure what makes them a fan favorite, but we do know that with the WX P-17 we must be doing something right.
