The title may seem kind of funny, but I am completely serious. Has anyone tried underarmor products as underclothing for either cold or hot weather? I have never tried them, but I have seen them and thought about it many times, and I was hoping to hear from someone with some experience with them. Do they really water wick? I have heard that in very cold temperatures sweating a lot can actually be detrimental. With that in mind I am trying to pick my layers carefully.

Also, I noticed they make cold weather water resistant gloves. Despite the price I have been more interested in seal skins gloves because they claim to be very cold resistant and completely water proof.

Before I went ahead with any of these assumptions, I was hoping someone might have experience with any of the above. Thanks!
