Im doing a walk on sunday called the High Street up in the lakes near Helvellyn.
Was out today on a geology field trip using a Fishing Jacket, but its a bit long & a Helly Hansen Jacket that my Step dad has (bought from a walking/hiking store) would be better.
Anyway, although he has used it in rain, he doesnt think it is fully waterproof, I think it would be as it looks it & he hasnt had problem with it, also I dont think they would sell expensive walking jackets like it which arent.
I'm going to try & get my own tomorrow in Town but if anyone has any idea about it then let me know. Are they generally waterproof?
