Heh, well you have a point there. But it's likely to end up as litter if the wind takes it, and the sleeves and hood leave something to be desired.
> Seriously though, all running waterproofs are sweaty (i.e. less breathable and more waterproof) or leaky, unless you work hard and get hot (i.e. more breathable and less waterproof). Haven't found a perfect one yet!
I think you're right there, but I've never tried a hundred quid one.
I have a couple of those Decathlon cheapies kicking about in my van usually, they're handy when caught out in a downpour without a proper jacket. But for running I generally use one of the even cheaper offerings that pop up occasionally in the aisle of wonder at Aldi or Lidl. (They tend to the "less waterproof" end of the scale, but keep the wind off and do fine for the relatively short distance/duration running I do.)
