Disclaimer that I work for VF, their parent company. That being said I don't work for TNF and I'm brutally honest. (often to a fault). Their down and synthetic (thermoball) insulating layers are solid per the above comments. Futurelight is really picked over (sold out) at the moment but excellent new technology, super light and way more effective breathability than any other membrane systems on the market. Look for all the new Futurelight winter gear to hit the TNF site around November. If you are a late season hunter I'd consider this. Finally on the equipment side I don't like their tents but they launched an excellent new bag this your called "
The One". It is a bag system that takes you from 5 to 40 degrees with a zip on top quilt. With 800 fill down and under $300 it's also an insane value. What's especially good about hunting with this bag is the top layer that completely removes to make for a nice packable down quilt for warmth while glassing. It even includes a toggle closure to keep it around your shoulders in this configuration.
Other brands in our envelope that may be running first responder discounts (haven't checked) that are awesome: Smartwool and Icebreaker. Icebreakers merino is my absolute favorite, base layers are insanely comfortable and warm. Icebreaker also makes my favorite merino t-shirts for hunting, crazy lightweight and comfortable as the next of skin layer. Smartwool is better on the sock front.
