For 30 bucks you really get 3 pairs of sunglasses with this product.  you get a dark lens set for those bright days, a brown lens set for those partly cloudy days, and a yellow lens tint for those darker overcast days.  I got these for my college baseball season and they worked awesome.  they are lightweoght and will not fall off your head no matter how fast you run or how hard you fall, they are on your face, man.  the lens clarity is not bad at all and they certainly helped me find the ball easier with them on.  Also, the frames are durable.  one of my teammates stepped on them with cleats and ruined my brown lenses but the frame was completely unscathed. i also found it difficult to spend 150 bucks on oakleys for this exact reason.  its better to go with some cheapies when you know youll put them through a thumping.

these sunglasses also look very cool.  they are sporty looking and i'll even alternate them with my maui jim glasses for casual usage.  the lens shape is definitely favorable and because the frame does not continue along the entire lens, blindspots are eliminated.  this aspect is key when playing a sport as reactions are critical to peak performance.  Changing the lenses is also extremely easy and can be done in between innings if the weather happens to change.  Easton provides a pullstring microfiber pouch to store the lenses and glasses themselves, a nice touch from an excellent company.  I just keep it right in my baseball bag in case i need them.

i highly recomend these high value classes for any baseball or sports player or for those who just need a durable and versitile pair of shades that could possibly take a beating.
