The Fanatic Bib is the most advanced sound-suppressing fabric in the hunting world, built for warmth and windproof protection on cold winter days where stealth and body temperature are critical. A Berber fleece face silences the GORE-TEX INFINIUM™ with WINDSTOPPER® Technology barrier for 100% windproof warmth while 133 g/m2 Primaloft® Silver Insulation traps body heat. Low-bulk hems and full side zips allow you to step into the bibs in your stand without having to take your boots off, and they quickly and quietly allow you to dump heat when needed.

Why We Made This

We saw the need for a late-season bib that could withstand cold days sitting in the stand while providing the most advanced visual and auditory concealment. Our approach was to design a bib that would protect you from not just the cold but the wind, while minimizing the noise created from layers of gear. Working with animal scientists and ungulate specialists and using controlled laboratory tests, we developed the warmest, quietest bib on the planet by utilizing a GORE-TEX INFINIUM with WINDSTOPPER® barrier sandwiched between Berber fleece face fabric and Primaloft® SIlver insulation. This updated fabric package is half the audible engagement distance as compared to our previous Fanatic line. Additionally, we incorporated compression-resistant insulation in the seat to create a shield from vital heat loss.

I love everything about the fanatic bibs except the elastic shoulder straps. I didn't realize they would get destroyed by the ozonics ozone generator. Not a good day for me. If you don't use ozone then the straps are awesome.

Bibs are great and I'll give them a four star only because I wish that they put a little more insulation in the lower leg area, and they didn't put a pocket at the top of the bib for like 'phone- map'- etc'

I have a question.. How are these in the rain? I’m waffling between this or the incinerator and can’t make up my mind

The fanatic bibs... Wear do I start with these babies. Being a freeze baby in ne Ohio I get cold easily. But I like to hunt a lot. So far this year the low has been 18 and wearing my heavyweight bottoms, stratus pants and these bibs, my lower half has not even gotten a chill. Super quiet, soft, pockets, I even asked my wife if they made my butt look big and she said no. Lol. Yes they are expensive, but yes they work. But don't make the mistake of thinking I'll just buy the bibs and coat and be warm... It's the whole system that works together to keep your warm. Also whatever size pants you wear in the ews, or stratus, or whatever... Continue with that same size as you proceed to the next layer. Sitka has taken that into consideration. When I'm all layered up, everything fits perfectly. But if I just put on the bibs or coat without the layers, they're big on me. If you want to hunt longer into the season, and you can afford it. Do it. I've never done a review before, but after getting thus whole system, I was so pleased that my wife said I needed to let other people know as well.

These bibs are phenomenal. They're warm and quiet. Spacious, but not baggy. if you could ever want a pocket, its there. Absolutely love them for cold sits in the saddle

The nicest piece of hunting apparel you will ever own. Yes Sitka gear is more expensive but it is seriously that much better; ever little detail is thought of. I am 6’6” 200 pounds and ordered an XL and was swimming in it, hassle free exchange for a large tall and that was perfect. I have fanatic bibs, coat, and hat and love them all!

Beyond the Layers - Athlete Jim Hole Jr.

In the deep winter freeze of the Alberta Bowzone, where late November temps can reach -40F, there are two considerations legendary whitetail outfitter and SITKA Athlete Jim Hole, Jr. prioritizes: keeping warm and completely silent to mimic the stealth and patience of an owl perched in a tree.
