At the beginning of this October, we are planning a trip in Scotland. We are mostly interested in trekking in the areas of Middle and North Scotland. I was thinking what to buy to protect myself from the rain - I dont have and currently Im not thinking of buying expensise gore-tex clothes etc., that are water-proof (I have some basic low-cost Quechua jacket with NOVADRY technology which has water column of 5000 mm). I found out, that army ponchos are pretty reliable against the rain - there is for example this one Czech army poncho , which is quite affordable for me.
The question is - is wearing poncho good idea in Scotland? Ive heard, that I might have some problems due to wind in Scotland while wearing poncho. Will I be able to walk with it or not?
If not, could you recommend other way of affordable rain protection?
