Well I went a different route and bought a pair of these in medium
http://www.amazon.co.uk/Ronhill-Mens-Bikester-Evolution/dp/B0068XN6IQ (not sure why it says £21-£60, highest price is £25 for the small) and then bought a pair of padded undershorts for underneath
They aren't elasticated at the bottom but aren't overly baggy either I just tuck them into my cycling socks if Im worried about them getting caught
It might not be the most pro look ever but I don't give a hoot about that, for commuting, recreational rides long distance included its been fine for me and spent about £40 in total, as the undershorts were half price
