Perfect weight for cooler days – as a three-quarter length they're comparatively heavy – and extremely comfy. But they have no drawstring so have a tendency to shift down. I had to pause a couple of times mid-run to hoik them up again. And the small pocket at the back is open from the top – no envelope-style fold, no zip. It might be fine but I don't trust it enough to stuff my only set of keys in and run off-road.
Very comfortable but badly needs a zipped pocket. If they had that and a drawstring they would be excellent running tights.
