Colesy, i've got a couple of pairs of Oakleys that i use for cricket and as brand they are fantastic.
However, im not convinced that this particular model would be that suitable. Firstly there are no rubber 'ear socks' on the arms of the glasses and this makes it more likely that they will fall off your bonce when you're running in the field etc.
Secondly, the lenses arent interchangeable, which i find is the Oakley's ive gots biggest asset.
Hope this helps, if youre looking for oakleys at a decent price for cricket then look on ebay. Get some lovely M-Frames at decent prices on there from time to time.
