I got a set for Christmas and used it late-season bowhunting. It's amazing stuff. No matter how much you exert yourself, there is no clammy, sweaty feeling afterward. You always are dry and comfortable. It fits like a wetsuit, skintight. On the set I got, it said that it is to be worn only in 45 deg. or lower temps. Above that, you'd be too warm. It is designed to be a base layer, so I don't think camo would be necessary.
