havent had to go to the heavy stuff quite yet but got a UA shirt that is getting close, well prob closer to the garbage can.... thanks for the ideas!
Try Justin Charles merino wool layering system. Naturally no odor, very warm even when wet(none of the synthetics can do that). It's premium stuff but you want be coming out of the woods early because you are cold, wet, or SMELL. Merino Wool naturally regulates your temperature better than most of the high tech stuff it is called the perfect fiber in it doesn't collect or have an environment conducive to odor. If you are a bow hunter you are probably looking for warmth without bulk, something that will dry out fast and yet is still light and odor free. They have a light weight, mid weight, and heavy weight no itch, very soft to the skin. If you do sweat, it naturally evaporates within 10 to 15 minutes but not synthetics they stay wet for the duration. Over the last 30 years I've tried just about everything. The company has 100% satisfaction guarantee policy also. Buy the light weight first, then the mid's and depending on how cold it gets in your area get the heavy. My outer clothing is Scentlok. Hope this helps some one. www.justincharles.com
