Word of caution about the polypro stuff. If you put it in the dryer make sure you have it on the lowest setting as the synthetic material melts and seals all the wicking pores up. You really can't see too big a difference, but it feels stiffer and pills up. Turns it into a giant sweat suit. I learned this from experience. I ruined a set of polar weight thermals this way. I still wear 'em to remind me how stupid I was. Every time I shiver I cuss myself. I quit drying my polypro stuff and the static cling is bad too. I had three thickneses (light, medium and heavy weight) of polypro and when it got cold out I would layer them, they were impossible to put on due to the static cling. I'm going to try UA this year, but I won't throw out my other stuff yet.
