Insulated bibs
When the temperature drops into the teens and the wind starts cutting through the hardwoods, a standard pair of pants won't cut it. For a big game hunter, insulated bibs are the ultimate "sedentary" gear—designed to trap a massive column of warm air around your core and kidneys while you sit motionless for hours. The debate usually comes down to "bulk vs. warmth": do you want to feel like a marshmallow but stay toasty, or do you want high-tech, low-profile insulation that lets you move?
What Separates Good from Great
Windproof Membranes
In extreme cold, "insulated" doesn't mean "warm" if the wind can blow right through the fabric. A "great" bib features a dedicated windproof barrier (like GORE-TEX INFINIUM or Kuiu's wind-blocker). Without this, even 200g of insulation will fail the moment a 10mph breeze hits you.
Full-Length Side Zips & Drop Seat
Bibs are notoriously difficult to put on in the field. High-quality bibs feature side zippers that go all the way to the hip, allowing you to zip them on over boots at the base of your stand. A "drop seat" or "C-zip" is also a lifesaver for mid-day bathroom breaks without having to shed your entire upper layering system.
Body-Mapped Insulation
Cheap bibs are stuffed uniformly, making them bulky in the joints. Great bibs use "mapping"—heavier insulation in the thighs and seat (where you lose heat to cold metal stands) and lighter insulation in the crotch and behind the knees to prevent bunching and allow for a clean climb.
Silent Face Fabric
Many "warm" bibs use a nylon shell that crinkles in the cold. Since insulated bibs are primarily for close-range whitetail or stationary elk hunts, a "great" pair uses a high-pile fleece or "berber" face fabric that remains dead silent even when the mercury hits zero.
The Call
Specifically designed for the vertical hunter. It uses a high-loft Berber fleece that is incredibly quiet and features a built-in muff for your hands. It is widely considered the warmest, most well-thought-out bib for stationary treestand hunting.
This is First Lite's "stay out all day" piece. It uses a combination of synthetic insulation and a windproof liner. It's built for the "dead of winter" when you're sitting in sub-zero temps and can't afford to shiver.
Kuiu uses a high-back design with suspenders that functions like a bib but feels like a pant. It's much less bulky than the Sitka or First Lite options, making it the better choice if you have to hike a mile before you sit.
A favorite on hunting forums for those who don't want to spend $400. They use 150g Thinsulate and are surprisingly quiet. They are bulkier than the technical brands but provide incredible warmth for the price.
While not silent, these are the toughest bibs on the planet. If you are hunting from a box blind or doing "work" in a cold camp, these Cordura-faced bibs will outlast every other item on this list.
