Hi! There are certain items I need for a 2 week long hike.
On the packing list that I was given it said that I needed a set of long underwear (tops and bottoms: wool or synthetic) and no cotton
I have no idea what that means, what it looks like, or where to get such a thing. It would be extremely helpful if someone could describe it and find a picture of it so that I could see what it is exactly and tell me where I can get such an item. Thanks!
On more thing that I have a question on is: what exactly are heavy socks (wool/synthetic)?
I got a bag of synthetic crew cut socks, is that appropriate?
Thanks very much! I am grateful for any help at all.
