In reply to PPP:
Yeah I found the jacket, but its too minimalist for me, as you posted earlier its the whole garment and not just a feature, I would need a chest pocket or 2, longer back etc. although i like the idea of this feature.
Once my ankle is healed I will have a shop around as most of the suggestions so far are for light weight summer jackets, whereas i would like to replace my winter jacket in the hope of an end of season bargain.
