I'm a fan of the Kamleika shorts too. I remember poking fun at them for years until I finished one race (langdale?) having got so wet that I was having to run holding my shorts up otherwise they would have been round my ankles with the weight of water they were retaining.
I bought a pair soon after and don't wear anything else if the weather looks wet. Also, great for wading through high bracken after a period of wet weather.
