Hi All, thanks
Sorry for not being clear, also was not aware that ones with inbuilt knee pads are not technically BDU's I have been look on military 1st and maximum I would be looking to spend would around 50 max.
I have to agree my post was very lazy so outlaid questions below for ease:
Best place to Buy Black BDU's looking to spend maximum of £50 all in?(like the idea of using work trousers with knee inserts)
Is it worth buying a set trouser with build in knee pads I.E. Viper tactical trousers?
Cheers guys sorry for being a pain
