I purchased the IWOM, Brutal XT hunting system while at the outdoor show last week. The system is well thought out and seems to be high quality. Every year I fight to balance warmth versus weight when selecting clothes for hunting during rifle and late archery season. For me this system seem to be just right. Yesterday I decided to test the warmth claims, 13 degrees and steady frigid wind 10+mph. I wore the suit over a T-shirt and a pair of thin Dickies work pants for a little over an hour. During that time I stayed completely comfortable and warm. I'm convinced it will work well over the long haul next season. Thought I would share this information for anyone thinking of upgrading or adding to their hunting gear. Thanks.
