I am looking in to a new setup this year for layering. I just purchased some cold gear under armour and have been wearing on several bow hunts this past couple weeks. Last year I wore polypro. for base layer but sweated to bad going to and climbing stand. From the 1st time wearing the under armour I knew it would be my base layer from now on. I was wanting to purchase a second layer for all day sets on stand as the seek/chase/tend phase's of the rut begin. I was looking at the polartec line and was curious if it was anything worth having. I welcome all input or ideas of other products. Thanks
