Ah, thanks for that. I suspected that might be the case... shame. However, I would only want to put the hood up on belays, not to climb with up. I wonder if the hood might just stretch over a helmet to that extent... Anyone?
There's a review coming very shortly on here, however the answer is yes. The material is super stretchy and sits tight to the head but will indeed pull up over my helmet, not that I ever wanted to do this.
