I have had a problem with it, wore it next to my skin. You don't want to get heated up with that stuff being the first layer, it doesn't wick, you'll have a very rough day ahead if it's on the way in. Put a good moister wicking material on first and it's killer. The wicking stuff makes you cold because of the rapid release of moisture and the fleece will keep the heat in. Thick poly prop is better than fleece, it does both. I still where the wicking materail. It's always first.

Tried some of cabela's silk this year, stuff worked well, but it doesn't dry well. Didn't seem to bother it for some reason.

Consider this, I have a lot of clothes. I have a lot of clothes that now fit my kids, some fleece. Buy clothes that don't shrink. fleece will. Or I'm now buying them gigantic. Had a hand made pair of wool socks made. The woman did a great job and at first I cused her when I put them on they were huge, she knew what she was doing. They fit great now.
