Agree, brand of fleece is not much of an issue. Brand makes a difference when it comes to pilling and other things for say a jacket you want to look presentable in. You will end up with several weights; from silk weight underwear to 200 or 300 weight but I can usually handle freezing temps with base layer and 100 weight - what some call microfleece (sold outdoor gear for years and I don't know where that comes from) but have not needed three layers. I just switch top layer. All under a windblocking layer-in this case the CP liner or any other jacket suitable for you activity. Hit some ski shops or chain sporting goods chains for some good deals. Absolutly everyone makes polypro, fleece and such garmets-it's all polyester anyway. Just don't use fabric softener when you clean any of it as it actually reduces its insulating function.
