Jacket needed... waterproof and very breathable

i recently got a black Montane H20 featherlite. weighs 42gm, packs down into a little bag, 100% waterproof, on sale at chainreaction £35. money well spent! :)

I got one of these for the Tour de France cyclosportive last year. Probably the best bit of kit I've ever purchased.

Trouble is, it packs down so small I've bloody lost it!
