In reply to Dr.Strangeglove: my Kamleika pants developed a rip surprisingly easily given the rubbery feel of them (brush against rock rather than major collision) but have been fine with a duct tape patch for well over a year. For running in they are by far the best waterproof bottoms I've ever had, the cut being designed specifically with this in mind I think. For summer use, compulsory fell race kit etc I use the tiny Montane Feather light stuff but for winter fell runs, KIMM, etc where there is a high chance of actually needing an outer layer on the legs the Kamleika are hard to beat IMHO. I prefer my Haglofs Oz top to the Kamleika smock my mate uses - better cut, better feel, more element proof AFAIAC
