Hi diweste,

Generally speaking,the best thing for your friend to do is to increase his knowledge base, it weighs (and for the most part) costs little as well.

Please invite your friend to spend some time on Equipped To Survive Forums and look around. I'm forever poking around looking at various threads and links, the older threads present a great amount of shared wisdom.

The previous posters have made several excellent suggestions as well.

Regards,
