@CLJ:

Measure your Levi's jacket in the way that is demonstrated in the forums and then compare those measurements to the [specifications listed for the 526J. The size with the closest measurement spec to your jacket will probably be that of best fit.

thanks, looks like i'll go for an L then :)](http://www.ironheart.co.uk/jackets/ih-526j.html)

Hi,

I'm considering buying a 526J, but not sure with the sizing.
I wear a Levis trucker sized S, should I go for M or L?
Thanks.
