While I can't recommend sewing your own outdoor clothing, and I don't like sewing myself, I have made a few simple things. A sleeve from an old thermal shirt became a one-ounce ski mask with scissors and three minutes of sewing. Socks with finger-holes became nifty hand warmers. As an insulating layer, I have worn a four-ounce piece of poly-batting like a tunic under my jacket, to the top of many mountains. Finally, without too much sewing, you can often modify your old clothes to make cheap outdoor clothing.
Maybe you feel trouble to purchase a delightful North Face jacket in a specify shop and want to get it in other outlets, you need to know how to discriminate the genuine commodities and sham. More and more illegitimate venders in order to make money, they will imitate some brand clothes or others and sell them in a lower price. So does the North Face. The illegitimate venders will make quite a few profits by manufacturing the imitations, just because the consumers do not see how to keep yourself from being scammed. There are much spurious evidence of the imitations that you need to distinguish how to use it.
