Not easy to get Hein Gericke gear in my neck of the woods, so I bought a pair of Airstream II trousers a month ago from Belgium. With the euro in the doldrums at the moment they worked out pretty cheap: �40 including delivery to the UK.

They are nicely put together, are cool to ride in, light weight and comfortable to wear as off the bike. Only drawback is they're black, which isn't the ideal colour to be wearing in bright sunshine!
