Champ188 knows this, but I will never, ever, ever be without the UA ColdGear Infrared base layer again. I have the tops and bottoms and the matching balaclava, which is a prized possession. In the market for some quality fleece / flannel lined jeans and a fleece lined flannel shirt. Until I find the ones I want and that fit (and while it's this cold) I put a pair of Cabela's 100% polyester MTP Polar Weight thermals on over the UA base layer. It's fleeced on both sides. Finish off with regular jeans and a UA Borderland 1/4 zip long sleeve hunting shirt. Good pullover hooded sweatshirt. Of course you can't leave off the GoreTex. I currently have Cabela's Guidewear jacket and bibs. We got them half-priced a few years ago. I drool every time I see the TV pros wearing Simms, though. Wool socks and Thinsulate boots.
Sounds like a lot, but each layer is thin which really helps with the layering. In the market for gloves. Been wearing some fingerless gloves from Cabela's. Pretty good most of the time, but I lost the feeling in my first two fingers Saturday. Took awhile to get the circulation back. Looking at reviews on the UA NoBreaks ColdGear Infrared Liners. I'd love to hear some recommendations on waterproof / water resistant form fitting gloves you can fish in.
