I saw these in Cunninghams in Ambleside the other day, anybody own a pair? https://rab.equipment/uk/kinetic-alpine-pants
I have had a pair for a few months now. Nice fitting, not really an overtrouser as a bit close fitted, but work over running tights etc well. I have used for shorter walks up to two hours and have stayed dry, breathability is good, and comfy to wear. Also used for the odd really wet run and they work well for that as well.
