FYI: what about PolyPro

I've used it once or twice and have initial impressions
Size Bought:
6' 5"

The main benefit of polypropylene as a fabric is its moisture transfer abilities; this textile cannot absorb any moisture, and instead, moisture passes through polypropylene fabric entirely. This attribute allows moisture that is exuded while wearing a polypropylene garment to evaporate much more quickly than it would with a moisture-retaining garment. Therefore, this fabric is popular in textiles that are worn close to the skin. However, polypro has a tendency to absorb and retain body odors when it is used for undergarments, and it also melts at relatively low temperatures. Molten polypro fabric can cause serious burns, and this issue also makes it impossible to wash this fabric at high temperatures. Polypropylene fabric is one of the lightest synthetic fibers in existence, and it is incredibly resistant to most acids and alkalis. In addition, the thermal conductivity of this substance is lower than that of most synthetic fibers, which means that it is ideally suited for cold weather wear.
