Has anyone sourced for a male zip offs that zip off above the knee. I find that when I zip off the zip can rub on the knee and if you roll them up you end up with the bundle rubbing above the knee. I have Ex-officio pants. I have heard female pants solve this but is that so? I have hiked a fair bit in the US where shorts and tights are mostly used but then when it warms up you have the issue of taking the pants off to take off the tights .
