In reply to bigdelboy1980:
i have used the omm jacket for mountain running, cycling and orienteering, i find it gets sweaty inside when working hard but also wet fabric on the outside which takes a long time to dry and would freeze in cold weather. When wet the fabric also feels cold. I had a light weight gortex cag during a wet OMM race and my partner had the kamleika top, mine had dried by morning but his was cold and wet inside and out. On the plus side it is stronger than it feels as I have never ripped it despite snagging on thorns rocks etc. but overall i wouldnt trust it if in a serious situation.
