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.

This is the warmest, quietest gear I’ve ever worn. Rain, snow, sleet, I’ve stayed more comfortable and more quiet than ever before in the stand, for hours on end which has led to more all day sits. Another impressive quality of this gear is that there are pockets everywhere so storage of important gear isn’t an issue. You get what you pay for when it comes to gear and if you’re looking for the best, look no further.

I put this suit through enough to feel comfortable to make a honest review. I bought one in March after talking with a couple buddies who had already purchased one. I hunted Illinois gun season Friday 8 degree wind chill, Saturday 12 degree wind chill, Sunday morning 12 degrees, 3 degree wind chill and wasn't cold at all. Obviously my toes and hands took a little beating but the rest of me was warm. We even had 30 mph winds. I wore a base layer, mountain pants on the Fanatic bibs. Top was the core hoody, ambient hoody, and the coat. The angled zipper takes some time getting used too but the full front pocket is great for your hands. The pockets are in the right spot for me, big enough to get my hands in with gloves on, and nothing falls out of your pockets. For the nay Sayers talking about money, how many clothes you have to wear under it, etc. You'll spend more trying to layer under other systems. I am so sold on this suit I bought a second one for a back up and alternate for scent control. Don't wait to buy this suit. Just buy it. You'll be glad you did.

I bought my first set of bibs 7 years ago and decided to buy these(even though the others were still perfect.) I hunt ohio late season and it gets in the negatives with the windchill.

I own or have owned nearly every piece of Sitka gear in the whitetail line. I really like these bibs, and the best version of the three versions so far. I wear an XL. I’m 5’9”, 36” waist 47” chest, and broad shouldered. I can wear a large, but where I run into size issues is the legs when layering. I usually tighten the belt up all the way. I hunt in Wisconsin, but don’t break these out until it’s below 20*. I also pack these in most of the way, or if it’s a short walk I unzip the front and vent the legs. These bibs are not meant for walking long distances in, nor are they meant for crashing through brush. They are meant to be worn stationary and be silent, which they excel in. I wear the bibs over the top of a base layer and the Equinox pant, and this gets me down well below zero.

This is by far the warmest hunting gear I’ve ever put on. Last weekend I sat in the stand, temp was 20 degrees with a 15-20 mph north wind and was warm the entire time. Today I’ve been in the boat with rain, sleet, and snow, and once again never got cold. From all my SITKA Waterfowl gear to my new Fanatic set, you can’t go wrong with the SITKA name. This stuff completely blocks the wind and holds in your body heat. If your looking for cold weather gear, this is the ticket!

Great bibs. I was warm with fist a base layer and the Fanatic Jacket, temp was in the upper 20's - mid 30's (so two layers). The only negative is that I got a pull on my knee the fist time I wore them. That being said, I was also dragging a huge buck that wanted to stay in the woods dead or alive and there were some thorn bushes. My only advice is some long warm socks, some of the insulation end around the knee. I love the set, cannot wait until I can wear them again.

Just buy these! You will NOT be disappointed. However for those who would like additional details, the bibs are incredibly warm and comfortable for using in Wisconsin archery and rifle woods in Nov/Dec freezing temperatures. Should help you stay in the woods longer. In addition to the comfort, the bibs are ultra quiet and offer substantial pockets for storing any gear you wish to have handy.

I absolutely can’t believe how good the Fanatic System is. First off my body gets frozen in around 30-40 minutes in 50°F weather if I stop moving around. Wearing the Fanatic Bibs and Fanatic Jacket even with some junk Walmart base layers under my Sitka Mountain Jacket and Timberline Pants, we got down to about 20°F and I sat for 4 hours with just a little tiny chill. But I’m convinced if I had proper boots to keep my feet warm I would have been perfect. I have had a successful hunt this year with 3 more tags to fill and I really have Sitka to thank. If I didn’t spend the money on the right equipment for the job this year with Sitka I wouldn’t have been able to sit. Yeah I can torture myself and freeze with the other hunters but for me, it’s not ethical to take a shot when you’re shivering so bad you can’t hold the rifle steady.

ALSO: these things DO NOT stain, I was amazed I washed my bibs and accidentally got some blood on them and the blood came right out. I washed on medium temp with NO detergent or soap. The blood washed out with water I couldn’t believe it, especially after it had sat on the bibs for 10 hours before I finally made it home and got them in the wash.

JUST SPEND THE MONEY! Not only will you not regret it but you will be happy you spent the money on Sitka.

Excellent heavy weight bib. Unbelievable variety of pockets and hand warmers. -7°C and strong north winds didn’t keep me out of the stand and it paid off. The breathability scale may be a little off though… if you’re active, you’re sweating. Regardless I 100% recommend buying.

Its so warm, comfortable and quiet as can be. Gone are the days of 2 base layers with 2 pairs of pants. Easiest pants or bibs to put on with boots that I have ever tried. Pretty expensive but I have no regrets because I should never need another pair.

My favorite piece of gear is the fanatic bibs and jacket. I am a bow hunter and this is exactly what the doctor ordered. Extremely warm. If Temps are In the single digits I just add an equinox hoodie or the Celsius middy And there’s nothing I can’t handle for an all day sit. Everybody complains about burs From walking through brush on recoveries. I have not wore my hunting clothes on a recovery in 15 years as I know better than that. That’s how you destroyed good clothes with thorns and Breyers and burs.

I always give the deer time to expire. I always walk back to the truck and throw on my carhart bibs and jacket. Then go back in for the recovery even if my walk is an hour out. I understand some guys don’t have this option and I get it. But if you do have the option to get out of your hunting clothes before you start tracking.

Probably the best designed product in the entirely line up. The only thing that should be added is waterPROOF. If the incinerator series could crossbreed with the fanatic series it'd be a winner.

I like the idea of no fleece where the burrs stick, and it mostly works. Good pockets for holding cellphone, accessories, headlamps etc. and I really like the external pocket for slipping stuff I access often in and out of. The only 2 fixes I would suggest is actual full length zippers like on the incinerator and that way your boots wouldn't get mud all over the inside when putting them on at your tree. They could be a little warmer, there's really not much insulation.

These were the first quality late season camo hunting bibs I had ever purchased. They kept me warm in the stand and gave me enough warmth to bag a late season buck with my bow last November. They do seem a little bulky. The biggest drawback I noticed is that they are so warm that you either have to pack them out to the stand or have the side zippers fully open if it's really cold to prevent from sweating. I do like the zippered legs for venting/heat regulation. Overall, a great product that is very quiet and keeps you in the stand longer during frigid northern WI winters.

Very poor construction and warranty on this pant. The puffy looking material is actually very thin and tears easily allowing the insulation to come out. Mine tore within a couple months of purchase, only wore them half a dozen times, still don't know exactly how the tear occurred because I didn't notice it when it happened. Sitka did not cover this under warranty, their warranty is basically useless. If you are in Canada they send you a url for a company you can pay to fix the pant. They do not have the quality or warranty you would expect paying this much for a pant. I will not be buying any more Sitka gear after this disappoint.

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.
