does the Montane have any waterproofness about it, or purely windproof ?
I’m assuming the Montane will be similar in performance to the Buffalo.
Like the Buffalo it’s Pertex with pile, so breathable and relies on the really tight weave to repel most water. The interior pile means you don’t get wet feeling unless it’s monsoonal.
The only time I’ve felt the need for more protection was in a ‘Puffer 24hr where there was prolonged heavy sleet and wind on parts of the course, and I solved that problem by chucking on another Pertex shell (Montane cycling one).
The rest of the time it’s all you need, and a few hours of ordinary rain isn’t going to bother it IMO.
It may be ’80s tech, but I trust it.
